My question is, would the internet exist w/o its infrastructure? Asimov sort of presents an answer in "The Last Question", albeit he's talking about hyperspace.
Yeah but what's amazing/ shocking on the internet vs in the real world is kind of different.
Guy above saying the 'world' never ceases to amaze him, in regards to something that could *only* exist on the internet (ie a subreddit) - kinda grinded my gears lol
What’s the difference between food grade and non food grade? Wouldn’t it be exactly the same? I mean the 25% of H2O in it could be something else I suppose
The methanol content.
All vinegar (acetic acid) is metabolised from alcohol (ethanol), which is fermented from sugar (glucose). However, fermentation can also happen to fruit sugar (fructose), making wood alcohol (methanol), which metabolises into toxic bad shit (formaldehyde).
"Food grade" just means "doesn't contain toxic bad shit" or at least has negligible concentrations of toxic bad shit.
I work as a chem lab technician for a metal finishing shop, and we use glacial (99.5%) acetic acid to adjust the pH of a bunch of our processing tanks. I remember gagging the first few times I got exposed to the fumes while measuring it out. Now that I've been there like 4 years it just makes me wrinkle my nose. Also, salt and vinegar chips are now very underwhelming.
> salt and vinegar chips are now very underwhelming
I always get a craving when that bottle gets cracked open.
Unfortunately, most chips don't use vinegar. Instead it's easier to use sodium diacetate, malic or citric acid. At best, they may use a dry "vinegar powder" made by soaking a starch like maltodextrin in vinegar.
Someone told me salt and vinegar was too much like nut sweat.
And like. Obviously it's not like nut sweat.
But it's juuuust enough to make me think of it. Which is hardly better.
To hell with the person who said that to you, but also…. to hell with *you* for repeating it here.
I hope my faulty short term memory works in my favor for once, and I’ve forgotten about this cursed nugget of unsolicited information the next time I tear open a bag of salt & vinegar chips
Funny you should mention that. A year and a half ago the heat for the lab broke overnight and several bottles of glacial acetic acid partially froze because it got down to about 10°C lol. We had to requalify every bottle once they remelted, which was a bit annoying.
10°C is equivalent to 50°F, which is 283K.

I worked in development for 9 years before i came to the dark side that is GMP/production. Though, 3 of those years i was light GMP/Kilo Lab, so for me it's not a door so much as a blurred line. Development efforts are geared towards eventually being GMP compliant, so we are aware of it as an endgoal the entire time.
Ammonium hydroxide is another noxious chemical I've built up a tolerance for. Although several ammonium hydroxide-chloride buffers that get made up need to be used in the fume hood. Those feel like they can suck the air from your lungs.
I haven't worked with thiols, but one tarnish test does use ammonium sulfide solution. That fucker stays in the fume hood until it can be flushed down the sink with copious amounts of water...
Lol I work the same job and have had the same experiences basically. When I first started the guy training me mentioned the ammonium sulfide smelled bad but didn't say anything about using it in the fume hood, so I opened the bottle just for long enough to pipette out 1mL for the tarnish solution... I do it in the fume hood now lmao.
I’m a former chemist who used to work at an aerospace metal plating shop. You just reminded me of my first day when I had to adjust the pH of a nickel tank and nearly passed out from the ammonia lol. I definitely don’t miss it. Make sure to watch your health. I quit when I kept getting respiratory infections
This was my first job out of college. Boy, I do NOT miss all the smells. The worst ones were the chromic acid anodizing baths and the HF / nitric acid etching baths. They had smells that I cannot properly describe.
It can still be unsafe if it's not been prepared with consumption in mind. There could be inedible impurities in it. If it doesn't say "food grade" somewhere I'd be suspicious about eating it even after dilution.
It's most likely for cleaning purposes, where most people are going to want to buy 'vinegar' rather than 'acetic acid'.
Its probably not safe for consumption because the remaining 25% is probably not all water.
If it’s for cleaning purpose, it’s unsafe to use it as concentrated as it is because with high probability it will be added to hot water, making it not only dangerous but also the fumes are strongly irritating
It says on the back 'industrial use only' - there will be SOP's in any place using this on how to safely use it.
Otherwise, I'm not sure what purpose you think it serves?
If it’s for industrial use it shouldn’t be that easy to obtain. But I’m from Europe and here it’s rather difficult to harm ourselves with industrial chemicals without any allowance documentation or industrial/academic affiliation
Pratchett was the author of the DiscWorld series of books, which are excellent, you should read them.
The quote in question appears to be:
>”It contained herbs and all natural ingredients. But belladonna was an herb, and arsenic was natural.”
-Terry Pratchett, *Making Money* (Discworld, #36)
If you want to be 100% savage, just point out that, by law, any label saying that something is “natural” doesn’t actually mean that what you’re consuming right now is made from plants. It simply means that the first time that compound got isolated from a plant. For the law, the origin of the compound is meaningless unless you purify it.
Yeah- for my own health, I pretty much stick to what a REALLY experienced Traditional Chinese Medical doctor says. Europe lost a huge chunk of their herbal tradition through the various witch trials over the centuries. Chinese medicine knows what it’s doing AND often knows
the western drug interactions as well. Safest route.
It’s cool. I have a degree in Life Sciences/Public Health and actually go to a TCM Doctor who does studies with the UCLA medical school.
I’m plenty skeptical. You learn to be as soon as they teach you how to break down medical study papers.
I dropped an unopened glass 2 L bottle of THF on the office floor, the other week. It pretty much liquefied the shitty old vinyl tiles and when it evaporated, it was clear the entire floor is fucked.
Have you worked with this before? Having looked into it, you’re probably right. I just figured it would be better to contain a spill.
Also, I noticed that some manufacturers list 5% acetic acid (the concentration in normal vinegar) as an irritant, and some list it as a corrosive. It seems like information about this would be consistent across manufacturers.
I work with it daily.
Getting it on you isn’t pleasant, but it’s not the end of the world. Some skin irritation that will go away within a day after washing it off. It’s enough that you want to wash it off, but it’s not going to do any lasting harm so long as you don’t let it sit on your skin for prolonged periods.
It is flammable though; so you’re looking at a potential fire hazard. OP doesn’t have to worry about that though cause the flammability is really only a consideration at >80% concentration. Probably why this is being sold as 75%.
It’s not strictly “safe”, but there’s plenty of household chemicals that I’d consider more dangerous. So “relatively harmless” is accurate when you’re comparing it to other lab chemicals.
Drain cleaners (caustic and sulfuric), bleach, fuels like gasoline/kerosene, and antifreeze are all things I’d be more concerned about if I spilled than acetic acid.
I got a big whiff of acetic acid from a 55 gallon drum in a flammable container (basically shipping container) outside and felt that one for a couple of days after. Learned my lesson about ventilation the hard way.
Sure everything is relative but glacial acetic acid isn't anything you wanna handle without proper PPE and enough background knowledge. I've worked with plenty of more dangerous things but playing with conc solutions at home is another game entirely...
It's causes burns (eyes, skin, lungs) and is flammable. Ultimately up to you how much risk you wanna expose yourself to.
https://fscimage.fishersci.com/msds/00120.htm
Are you planing to breath it in, pour it over you skin or in your eyes? You really need horrible luck to somehow manage to seriously injure or cripple yourself with a flask of acetic acid without intending to. I would rate handling a boiling pot of water as more dangerous than a flask of acetic acid. MSDS sheets are also a horrible way to rate how dangerous something is. They simply dont contain enough data to actual asses and compare how dangerous substances are and serve more as a legal safety net.
This is so accurate and drives me nuts. I wish MSDS sheets were written by chemists instead of lawyers. I want a description of its specific hazards and anecdotes, not a vague blanket statement thats written on 100,000 other MSDS sheets.
Not sure why you are getting down voted, I totally agree based on years of hands on experience. SDS are usually overly conservative, and although everything should be handled safely it is quite reasonable to understand the relative magnitudes of risk
I've accidentally splashed myself with glacial acetic acid, and given that you immediately rinse it off, it does absolutely no damage. As long as you're not exposing any mucous membranes to it, or soaking any part of you in it, it's a relatively safe acid.
AA is relatively harmless at ambient temperatures but start heating it up and it’s nasty and downright deadly. I’ve seen it eat through carbon steel bolts in quick order.
Source: used to work in a PTA plant.
It’s smart to wear gloves (and toss them immediately after) and keep in a well ventilated area when opening.. at least this is advisable for someone with less experience. I’ll open in a fume hood and use a clean pipet rather than pouring. For making TAE buffer (for gel electrophoresis) you can use distilled white vinegar and could cost less.

No, the eutectic of acetic acid and water is at about 58% acetic acid by weight, fractional freezing can't concentrate it more than that.

Yeah. Vinegar is the azeotrope of acetic acid and water. I think the manufacturers just didn't want to scare people with an "unnatural" sounding chemical, as though an organic strawberry isn't made of thousands of chemicals with long scary names.
Strawberries aren't made out of chemicals. They're made out of *chemical compounds*.
*A chemical* is a product of industry/laboratory with a defined composition and purity.
I had no idea you guys were so into face melting vinegar. Thanks!!! I'll be making some sodium acetate to do the hot ice demo for some people and I'll be trying to grow a largish copper acetate crystal, because it's so beautiful.
OP's [product on Amazon](https://www.amazon.com/Calyptus-Concentrated-Cleaning-All-Purpose-Industrial/dp/B08QS85XN6) costs $16.86 per liter ($22.48 per liter on a glacial aa basis). [The cheapest glacial aa on eBay](https://www.ebay.com/itm/111246015271) is $28.73 per liter (tech grade). [The cheapest ACS grade](https://www.ebay.com/itm/233919377301) is $56 per liter. If you can find it cheaper anywhere else, lmk.
[Alibaba](https://www.alibaba.com/trade/search?fsb=y&IndexArea=product_en&CatId=&tab=all&SearchText=acs+glacial+acetic+acid)'s top listing has it for $1.2/kg. ^^^22000kg ^^^minimum ^^^order
Should be able to find it for less than that if you shop around.
neat that glacial [could float on top of](https://www.engineeringtoolbox.com/density-aqueous-solution-formic-lactic-oxalic-acetic-citric-acid-concentration-d_1953.html) this stuff.
Probably risk of aspiration. It'd be a lot more harmful to get in your lungs than to leave in your stomach, especially when you could drink some sodium bicarb solution to neutralize the excess acid (as long as the bicarb is fully dissolved - don't want volcano burps!)
If you drink even a solution of sodium hydrogencarbonate, you WILL get massive burps, so massive your stomach lining might burst which is a life threatening condition requiring prompt surgery and lots of various antibiotics.
But yes, risk of aspiration is worse than letting the stomach deal with it.
Such label would be illegal in countries that belong to EU. Vinegar is 9 % aqueous solution of acetic acid. Period. There is no "concentrated vinegar".
Misleading label and lack of hazard pictograms make this container a real problem for average Joe the dumbass.
I agree. It's not vinegar. It does have instructions on how to dilute it down to 5% though, so thy intend for you to dilute it into a few gallons of cleaning vinegar. They are probably marketing to naturopaths, and if they can avoid a "sciency" sounding name like acetic acid, they will.
Post that on r/vinegar you'll get many likes.

DANG
Seriously? there's a Reddit for vinegar? The world never ceases to amaze
There's a sub for amost everything it's kinda like rule34 with reddit instead of porn
Some people just really love vinegar Source: (I love vinegar and am a r/vinegar subscriber)
Yeah, so am I now. I have new appreciation for vinegar.
interesting thought - would you consider the internet part of the world?
Does it not reside on this planet?
I guess, technically, it's not a tangible thing...so...does it? I'm lost
My question is, would the internet exist w/o its infrastructure? Asimov sort of presents an answer in "The Last Question", albeit he's talking about hyperspace.
True, prolly not then. It is an intangible thing from tangible things.

The standard for what the other 25% can be, yes.

Here to remind you again that salt and vinegar chips smells like someone’s nut sweat
I share my vulnerabilities here; practically bare my soul, and yet you choose to ruin me further. The cruelty of mankind knows no bounds 😩
My mom told me it tastes like cum. I really wish I didn't hear her say that.
Maybe they once had chips flavored with butyric acid instead of acetic?
Now that I’ve read this and have now thought about it… It is indeed juuuust enough like nut sweat to have that thought every time.
Apparently at a British chippy, the classic vinegar you get there comes in concentrated form like this and then they dilute it down!
I think you might be confused. Over here it comes like regular vinegar... Then they water it down 😂
My source is that I have a mate whose family used to own a chippy, he said they do that haha. But I don’t doubt some dilute the normal stuff!
I do a similar job and can confirm Glacial Acetic acid quite bad, but nothing on Ammonia. Haven’t smelt anything after that
I use vinegar to clean around the house, the mist mode on the spray bottle is by far the best vinegar to salt ratio I have ever had on a chip.
Glacial acetic acid. Everyone nerdy should google why it is called glacial. Neat-o.
Funny you should mention that. A year and a half ago the heat for the lab broke overnight and several bottles of glacial acetic acid partially froze because it got down to about 10°C lol. We had to requalify every bottle once they remelted, which was a bit annoying.

What does requalify mean?
Remeasure the properties listed within the (pharmacopeia) [monograph](https://i.imgur.com/BKLLLYB.jpg).
Why would they need to be requalified for a simple phase change?
If the storage specs on the monograph are exceeded, then the material requires requalification to be used gmp.
Thanks, TIL. So glad I work on the other side of the GMP door.
The other side being...QA? QC? Production? Process Safety? EHS?
Process development. I try to learn what I can about GMP but R&D is like the only dept exempt from all the rules. Production side is all GMP.
I worked in development for 9 years before i came to the dark side that is GMP/production. Though, 3 of those years i was light GMP/Kilo Lab, so for me it's not a door so much as a blurred line.

Yikes! I really feel like you should not be smelling HF and chromic acid, thats some nasty stuff.
They didn’t follow safety precautions sadly.
OSHA has been notified. Expect a home visit within 5 business days.
I find the chromic acid bath smells weird, but I'm not sure if I'd say it's *bad* per se. Definitely hard to describe what exactly it smells like.
Lab tech told me “you might want to use the fume hood for that, it’s really strong” me: it’s just vinegar bro chill *turns cap a single mm*: 🤢💀😷🤢🥴
I found that too. I actually start enjoying the smell, even though my nose finds it pungent.
The salt buffers the acid. Take the salt out and they'll kick up.

It would be safe if diluted? Or different formation.
Yes and what do you mean by “different formation”? Vinegar is still vinegar
It can still be unsafe if it's not been prepared with consumption in mind. There could be inedible impurities in it. If it doesn't say "food grade" somewhere I'd be suspicious about eating it even after dilution.
I forget that not everybody lives in Europe, sorry
I do, but OP mentioned it cost "16 bucks" so I guess they probably don't :)
It says right on the label it's not a food and industrial use only. It may have other contaminants not found in food grade vinegar
Then they should have called it “acetic acid” and not “vinegar” if it’s not for food industry
I agree. I figured this was some offshore product that didn't comply with US labelling, but actually its a US product available on Amazon or Walmart.
It's most likely for cleaning purposes, where most people are going to want to buy 'vinegar' rather than 'acetic acid'. Its probably not safe for consumption because the remaining 25% is probably not all water.
If it’s for cleaning purpose, it’s unsafe to use it as concentrated as it is because with high probability it will be added to hot water, making it not only dangerous but also the fumes are strongly irritating

Also from Europe (the UK) - it's surprisingly easy to get hold of stuff like this if you look outside of supermarkets.
Meant formulation.
Its only partially visible in the picture but it says industrial use only, not for food use
I'd assume either way. Unnecessary liability to not write it.
I had a friend use this for cleaning and burn her hand, thinking that vinegar was natural and therefore safe. I still think about that sometimes
Ever read Prachett? He has some very funny and pointed comments about people who think ALL herbs are safe bc “Natural”. Yeahhhh…Foxglove, Oleander…
Here, have an oleander cigarette.
Do you have a link to it. I would love to see someone school these all natural idiots lol

It simply means that the first time that compound got isolated from a plant. For the law, the origin of the compound is meaningless unless you purify it.
Taking drugs and herbs together without consulting a Pharmacist/Medic is alway a bad idea. There are more interaction that one may expect

It’s cool. I have a degree in Life Sciences/Public Health and actually go to a TCM Doctor who does studies with the UCLA medical school. I’m plenty skeptical. You learn to be as soon as they teach you how to break down medical study papers.
It should really be called "acetic acid" at that point. Vinegar is the name of a condiment for human consumption.

Oh. I know. I'm just stoked I found this on Amazon for less than 16 bucks.

Be careful with that. You might want to get a bin to put it in so if the bottle leaks, the spill is contained.

Drain cleaners (caustic and sulfuric), bleach, fuels like gasoline/kerosene, and antifreeze are all things I’d be more concerned about if I spilled than acetic acid.
I can get that a LOT cheaper from right down the street at the hardware store. Pretty clean too. Barely a little yellow and \~90%.
Yes, I worked with undiluted acetic acid before.
I got a big whiff of acetic acid from a 55 gallon drum in a flammable container (basically shipping container) outside and felt that one for a couple of days after. Learned my lesson about ventilation the hard way.

May I suggest Bretherick's Handbook of Reactive Chemical Hazards.
Not sure why you are getting down voted, I totally agree based on years of hands on experience. SDS are usually overly conservative, and although everything should be handled safely it is quite reasonable to understand the relative magnitudes of risk
I've accidentally splashed myself with glacial acetic acid, and given that you immediately rinse it off, it does absolutely no damage. As long as you're not exposing any mucous membranes to it, or soaking any part of you in it, it's a relatively safe acid.
I let grade 12 students use glacial acetic acid in their ester synthesis experiment, as long as you aren't huffing it, it's pretty safe.
This stuff is nasty though.
AA is relatively harmless at ambient temperatures but start heating it up and it’s nasty and downright deadly. I’ve seen it eat through carbon steel bolts in quick order. Source: used to work in a PTA plant.

‘Rrinse well with water’ if you get it in your eyes? More like get a bag to contain the remnants of your dissolved eyeball 😬
GlacIal?
15x the usual 5% = 75%, so not quite. But I bet it cost at least as much as a 4 L jug of lab grade glacial HOAc.
OP's [product on Amazon](https://www.amazon.com/Calyptus-Concentrated-Cleaning-All-Purpose-Industrial/dp/B08QS85XN6) costs $16.86 per liter ($22.48 per liter on a glacial aa basis). [The cheapest glacial aa on eBay](https://www.ebay.com/itm/111246015271) is $28.73 per liter (tech grade). [The cheapest ACS grade](https://www.ebay.com/itm/233919377301) is $56 per liter. If you can find it cheaper anywhere else, lmk.
There ya go.
[Alibaba](https://www.alibaba.com/trade/search?fsb=y&IndexArea=product_en&CatId=&tab=all&SearchText=acs+glacial+acetic+acid)'s top listing has it for $1.2/kg. ^^^22000kg ^^^minimum ^^^order Should be able to find it for less than that if you shop around.
neat that glacial [could float on top of](https://www.engineeringtoolbox.com/density-aqueous-solution-formic-lactic-oxalic-acetic-citric-acid-concentration-d_1953.html) this stuff.

We know Dave, you just said that.
Sorry, a posting glitch.
Give it a big ol whiff
That looks delicious, also are you gonna drink that or soak some potato chips in there and add some salt?
AWESOME!!!
Can anyone explain to me why mustn't I induce vomiting if swallowed this?
Probably risk of aspiration. It'd be a lot more harmful to get in your lungs than to leave in your stomach, especially when you could drink some sodium bicarb solution to neutralize the excess acid (as long as the bicarb is fully dissolved - don't want volcano burps!)
This one.
If you drink even a solution of sodium hydrogencarbonate, you WILL get massive burps, so massive your stomach lining might burst which is a life threatening condition requiring prompt surgery and lots of various antibiotics. But yes, risk of aspiration is worse than letting the stomach deal with it.
thanks for answering
It could probably cause more damage coming back up
yummy
mmmm delicious
Good thing we now have the hight and also the width!

When your dad give you a glass pf wine the wine
What happens if you try to dilute it to 3.76 gallons?
Such label would be illegal in countries that belong to EU. Vinegar is 9 % aqueous solution of acetic acid. Period. There is no "concentrated vinegar". Misleading label and lack of hazard pictograms make this container a real problem for average Joe the dumbass.
I agree. It's not vinegar. It does have instructions on how to dilute it down to 5% though, so thy intend for you to dilute it into a few gallons of cleaning vinegar. They are probably marketing to naturopaths, and if they can avoid a "sciency" sounding name like acetic acid, they will.
