What is the most powerful acid known?

 

[dextercioby]

"Normally" the perchloric & the permanganic ones have the largest first acid constant.However,IIRC there are some "exotic" ones (involving metals in complex combinations) which would have at least the same characteristics.

Do a google search.I'm sure u'll find out something valid.

EDIT:(personal remark) I would be really amazed,if someone proved me that the sulphuric one is not the most corrosive,ergo the most dangerous...

And google "Hammett acidity function" if interested.

Isnt anti-flouric acid more potent than sulfuric acid?

Im not too sure, But i remember reading this somewhere though...

What's "anti-fluoric"...?

Daniel.

P.S.Which means:"what's the formula...?"

I thought that HSbF₆ was the most powerful, but I might be wrong. It's certainly stronger than sulfuric acid.

Perhaps this is the "anti-flouric acid" referred to above? The correct name is hexafluoroantimonic acid.

I remember about that acid... But i still would not believe it burns literally everything...

A measure of the strength of an acid is not just how corrosive it is, but the availability of the proton associated with it. HF will eat away glass in short order, but in terms of acidity, it is far less acidic than HCl.

I was referring to corrosive acids.U missunderstood me.I'm still waiting for an answer (not necessarily from u) to the question i posted...Is there any more dangerous/corrosive acid than the highly concentrated sulphuric acid...?I mean with a stable molecule...

Technically, a proton accelerated using a particle accelerator.

All parts,though the thing you're implying is in the first.Those stuffs were faked big time.I still trust $H_{2}SO_{4}$ to be the "burning king"...

Daniel.

HF is almost certainly more toxic than H2SO4 though, but it's not because of the acidity, it's because of the F-. Also, nitric acid is in some ways more reactive because it is a better oxidizer than sulfuric.

I'm just saying that it's not as simple as saying "this compound is acidic, so it's will cause nasty burns."
