Any pH is possible so long as it fulfills the ionic product of water when you work out the concentrations of the ions present.
Still -3.6 sulphuric acid does sound unpleasant.

Pantywaists. I mix that shit with vodka and down three or four shots before breakfast.

>>1762444
but vodka tastes bad

>>1762417
I wonder if there is some free encyclopedia available which can explain basic terms like pH.

>>1762462
vodka barely tastes at all virgin
tequila tastes bad

>>1762482
>Pure water is neutral, and can be considered either a very weak acid or a very weak base (center of the 0 to 14 pH scale),
>0 to 14 pH

Yup, Wikipedia sure answers this question!

>>1762417

pH is a shitty measure of the actual strength of an acid, but I would sure as fuck not want to take a dip in -3.6 sulfuric acid no matter what chemistry tries to tell me.

>>1762488

> Measurement of extremely low pH values, such as some very acidic mine waters,[14] requires special procedures. Calibration of the electrode in such cases can be done with standard solutions of concentrated sulfuric acid, whose pH values can be calculated with using Pitzer parameters to calculate activity coefficients.[15]
AMAZING

Plus, the effects of acid on flesh don't get too much worse than those of sulfuric acid. It chars severely and rapidly.

The most acidic compound in the world is Fluoroantimonic acid, with a pH of -31. It is so strong, it burns glass, and you can literally dissolve water in it (assuming it doesn't have an explosive reaction with it, which it does).
This fucker is so strong you can't even store it for more than a few hours.

>>1762913
>Fluoroantimonic acid, with a pH of -31
I... I...

hold me

>>1762913
What is that even used for?

I mean, you could splash it on someone as a weapon and seriously ruin their day, but it's probably easier to shoot them.

>>1763067

Not everything is a weapon. Go back to /k/.

>>1763067
Imagine spraying it on a whole city of people.

Dear. God. Genocide.

>>1763067
Inorganic chemists jerk off to it. That's about it.

What do you even hold this acid in if it can burn glass?

>>1763086
magnetic fields?

>>1763086
Probably teflon, that shit is indestructible.

>>1763100
My waffles say otherwise.

They're fucking coated in it. I had to throw it out and buy a new waffle iron.

>>1762913
... I don't even

What about Alien blood? That shit has to be like, -231 pH.

>>1763116
Sorry to say this, but, It's just a frakkin movie.

>>1763142
But theoretically is it possible to create something as acidic as the Alien blood?

>>1763116
Trying to explain how their bodies would work with blood like that would give me a headache.

I suppose it could be contained by neon ice.

>>1763155

Also different acids go break down different shit. It's highly unlikely that this 'alien blood acid' would be able to cut through steel, brick, synthetic fibres, skin and tissue. A more suitable alternative would be something like dimethylmercury which goes through just about everything. If you get a drop of that even on your clothes you'll most certainly die. Although it'll take ages as the mercury poisons you slowly.

>>1763067
The stuff protonates saturated alkanes which helps stableize carbocations for industrial applications
>>1763086
When they use it in this manner they transfer it in pipes lined with teflon. The lining is replaced regularly.

>>1763155
No, it is very difficult to discover any stronger acids. Perhaps it is possible discover a stronger acid but, I doubt it will be much stronger. Refer to:
http://en.wikipedia.org/wiki/Superacid

Also, I must say,
>Rhomboclase, a rare mineral, is a solid form of sulfuric acid and ferric iron sulfate.
holy crap, never thought such shit existed.

>>1763175
You mean there are actually industrial applications? I thought it is only used for studying non-classical carbocations

If you mix fluoroantimonic acid with lithium nitride, what happens?

>>1763215
You get diamonds.

>>1763217
sounds legit

>>1763215
Everyone dies is what happens.

>>1763215
you get giant floating 4D shapes

>>1763231
>that filename
you silly /a/liens, always being silly in our little board

>>1763231
>that filename
oh /a/, u so silly

>>1763329
and ammonia

>>1763215
<--that
And LiSb6 or LiF + SbF5

<--that
And LiSb6 +NH3 or LiF + SbF5 + NH3

>>1763217
that doesn't make sense

how superacid + superbase = hardest metal known to man?

should not it be superwater and supersalt instead?

>>1763356
that's the joke.
are you fucking dense?

If we're talking about crazy dangerous shit, chlorine trifluoride deserves a shout-out.

”It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water-with which it reacts explosively. It can be kept in some of the ordinary structural metals-steel, copper, aluminium, etc.-because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.”
John Clark

This is now a dangerous chemistry thread.

Owing to its extreme reactivity, elemental fluorine was not isolated until many years after the characterization of fluorite. Progress in isolating elemental fluorine was slowed because it could be prepared only electrolytically and even then under stringent conditions, since the gas attacks many materials. In 1886, the isolation of elemental fluorine was reported by Henri Moissan after almost 74 years of effort by other chemists.[10] The generation of elemental fluorine from hydrofluoric acid proved to be exceptionally dangerous, killing or blinding several scientists who attempted early experiments on this halogen. These individuals came to be referred to as "fluorine martyrs".[11] For Moissan, it earned him the 1906 Nobel Prize in chemistry.[12]

>diamonds are the hardest metal
>secret trolling attempt

>>1763356
superacid + superbase = Dragonforce

Does anyone know anything at all about chemistry?

They probably meant to say pKa, which can easily be below 0.

>>1762511
Hyrdorfluoric acid is pretty bad shit to.
Seeps into your system and fucks with your nerves.

Mercury's pretty damn bad, even if it's obvious. Some can get into your bloodstream just by being on your skin and end up giving you permanent brain damage.

Silelence, you DEVIL!

elemental mercury isn't too dangerous. Dimethyl mercury on the otherhand, is INSANELY dangerous.

Dimethylmercury is extremely dangerous. Absorption of doses as low as 0.1 mL has proven fatal.[4] The risks are enhanced because of the high vapor pressure of the liquid.

Dimethylmercury passes through latex, PVC, butyl, and neoprene rapidly (within seconds) and is absorbed through the skin. Therefore, most laboratory gloves do not provide adequate protection from it, and the only safe precaution is to handle dimethylmercury while wearing highly resistant laminated gloves underneath long-cuffed neoprene or other heavy-duty gloves. A long face shield and work under a fume hood are also indicated.[4][5]

Dimethylmercury crosses the blood-brain barrier easily, probably owing to formation of a complex with cysteine. It is eliminated from the organism slowly, therefore it has tendency to bioaccumulate. The symptoms of poisoning may be delayed by months, possibly too late for effective treatment.

The toxicity of dimethylmercury was highlighted with the death of the inorganic chemist Karen Wetterhahn of Dartmouth College in 1997, months after spilling one drop of this compound on her latex-gloved hand.[4]

no. that's impossible you can only get somewhere near 16M sulfuric acid. Ph is actually the concentration of H3O+ so.. pure sulfuric acid would technically have a ph of 7 because the -OH and H3O+ concentrations would be equal.


I think in the article they meant the pka which is about that. The rocks would neutralize some of the acid and there would always be excess water because of the hydroscopicity of H2SO4

WHY THE FUCK DOES EVERYONE SAY ACIDS HAVE PH'S .... THEY HAVE PKA'S. UNLESS YOU STATE A CONCENTRATIONS, JUST SAY THE PKA. THEY'RE FUCKING DIFFERENT
