--Thrashed!--
...as we say in the midwest...
Honestly, though, we can't hold each other up to what we used to be when first starting on this site. To think - I didn't even know what a
coordination complex was back then!!! (I just used that excuse to a friend who was making fun of me for getting a 43.3% on the Local Chemistry
Olympiad - before I had taken chemistry....).

Iodic acid tastes less sour than I expected.
I sure hope nobody remembers my beginning.

So have any of these acids we've mentioned actually been tasted? I have to say I'm quite curious about the findings.

If you're just not interested in that sort of stuff, that's fine. But don't avoid everything drug-related simply because you're afraid that reading it
will somehow get you into trouble. Hating your health class just because you had to Google some info about illicit drugs is kind of silly, and wiping
your hard drive to erase all evidence of it is a bit extreme and unnecessary. You can read about illicit drugs all you want and there's not a damn
thing anyone can do about it. This includes detailed instructions on how to make them, too. Disclosure of that kind of information is protected under
the First Amendment of the Constitution.
Besides, there's a lot of interesting and rather useful chemistry to be discovered at "underground" places like Rhodium's Archive and the old Hive
forum. Say what you want about clandestine chemistry, but some of the most innovative and downright brilliant chemistry ever seen was ultimately the
result of a bunch of drug cooks trying to figure out new ways to get around the ever-increasing number of restrictions on reagents and precursors.
It's amazing how creative some people can be when given enough motivation. And what better motivator than recreational drugs?

OK. Here's a list of the ones I've tasted. (All as very dilute solutions)
Citric and Tartaric - Pleasantish "sour taste"
Salicylic - Slightly phenolic but pleasant.
Acetylsalicylic - A bit more astringent than salicylic.
Diethylbarbituric acid (we used to use this to make buffers in the lab). Faint smell and rather nice taste (V small amounts).
Acetic acid - vinegar.
Hydrochloric, hydrobromic, phosphoric, sulphuric and nitric. Strong "sour" taste.
Perchloric - Very astringent - goes beyond being sour.
There are a few I have or can make that I wouldn't try - Selenious and hydrazoic for instance.
If you're not part of the solution, you're part of the precipitate.

Interesting to read about this. Good that you did not try selenious acid or hydrazoic acid.
I hope you did not swallow any of these solutions.
Some other interesting ones, which are not dangerous at high dilution:
- ascorbic acid
- propionic acid
- malic acid
- malonic acid
- succinic acid

Lactic acid? Mucic acid? Those are others I'd be interested in. If I remember correctly, they're based on the structures of sugars, oxidized.

Based on the smell of lactic acid, I wouldn't want to taste it. Sort of like sour milk mixed with sweat, although not super strong.

- d-Ascorbic acid has a sweet component and is fairly mild.
- Citric acid has a bit of a fruity component to it, almost like it were sugar-free lemon juice or something.
- Malic acid is just sharp and sour. I believe Warhead candies are coated in malic acid.
- HCl is like puke, minus the food.
I have not tried any other acids. The above acids (except HCl) were USP food-grade when I purchased them, and I couldn't resist.
Oxalic, cyanuric acid, and benzoic acids would also be interesting, but form extremely insoluble salts or are very insoluble themselves. (Read: kidney
stones - be careful!) Toluenesulfonic acid probably tastes awful. Formic acid is probably pretty terrible too. I wonder if one can taste stearic
acid?
Someone should try hydrocyanic acid. It is said to taste metallic. Hopefully that person lived through the experience!

Can HCN really by absorbed if not swallowed?
Idk but I've seen stories of people trying to suicide with cyanide pills and it had failed so I was thinking maybe the conditions have to be just
right or the dosage must be high enough?

HCN is not something that I would play that game with. There are already enough fun things to try in this thread without inviting a death wish.

Oh yes. HCN can be absorbed by inhalation.
However, HCN is a relatively innocuous substance. It does have a small lethal dose for acute poisoning - in the region of 100 mg or less - but unlike
many chemical substances is not a chronical cumulative poison. Amounts well below the acutely deadly quantities are rapidly and completely made
harmless in the body.

Point taken, and well done as well.
I was a little deep in the bottle then and should not have been online.

Will it?
What kind of local damage does HCN cause? Is it corrosive to e. g. intact skin?

No and no. It's not corrosive, and it won't interact with cells
The cyanide ion halts cellular respiration by bonding as a non-competitive inhibitor, reducing the activity of the enzyme cytochrome c
oxidase. It's not toxic to cells, and its weak acidity causes it to be not very corrosive.
So a less-than toxic dose of CN^- will cause over-all less oxygen to each cell individually, so some of the weak ones will probably die sooner than
they otherwise would've, but cyanide doesn't kill cells directly.

Indeed. The most sensitive cells to cyanide poisoning are those most sensitive to hypoxia. Brain and heart.
On closer examination, it turns out that chronic poisoning of cyanide is possible after all - at doses much higher than acutely fatal ones.
The fate of cyanide in body is that it is converted into thiocyanate.
Two of the mechanisms of chronic cyanide poisoning include:
thiocyanate, though less toxic than cyanide, builds up to toxic amounts
production of thiocyanate exhausts body supply of sulphur in thiosulphate etc.
But local poisoning?
Cyanide absorbed or injected into local tissues would start being distributed around the body, as well as detoxified locally. Would a quantity too
small for systemic poisoning do any serious harm locally?

Doesn't it cause permanent inhibiting within the mitochondria it bonds inside?

I assume it does, yes. I meant "less than lethal", not "less than toxic" BTW. The cytochrome c oxidase is quickly replaced, cyanide becomes lethal
when cytochrome c oxidase is used up too fast for it to be replaced in time and too many cells die from inability to produce ATP.
