It's not really an acid but as I recall the most "acidic" substance is liquid boron.It's melting point is very high so anything you put it into will melt long before the boron does. It will also eat it's way through anything you put it in.I'll see if I can find the article I read.
The carborane superacid (H(CHB11Cl11), which is one million times stronger than sulfuric acid, is entirely non-corrosive, whereas the weak acid hydrofluoric acid (HF) is extremely corrosive and can dissolve, among other things, glass, and all metals except iridium.

lightarrow, just as a matter of technicality, your plumb is called lead in english.
I don't know why, plumb makes much more sense because the latin was plumbus and the symbol is Pb. I thought I might let you know just so no one gets confused. Oh, and just because I'm curious, what is lead in italian?
Anyway, more about corrosivity and causticity. What is causticity if corrosivity is how readily something reacts with a metal? How corrosive of aluminum is KOH? If it is strongly corrosive then I wonder why it took at least 40 minutes for it to react with the aluminum cans that we used to synthesize alum? It was 3 molar KOH. We scratched up the surfaces of the aluminum cans so that any paint or other coatings would not inhibit the reaction and it still didn't go quickly. Could it be possible that the can was made of an alloy of some sort with very little aluminum?
What is the best acid for quickly dissolving ferrous metals that is not too exotic and readily available?
Hi passionated Scientists, greetings from México, from the UNAM:I´m new in this page, but I'd like to help with this questionIt is well known for us that there are several strong acids like the H2SO4 or HCl, but reviewing in some books of Organic Chemistry as Mohrig´s I found there are some acids stronger than the sulfuric acid, I mean the called "superacids", see this page: http://en.wikipedia.org/wiki/SuperacidsYou can compare their ionization constants, for example for the triflic acid(trifluoromethanesulfonic acid) is Ka = 8.0 *1014 mole kg-1 CF3SO3H; for the Fluorosulfuric acid k= 10000000000 and for the sulfuric acid K1 = 2.4 * 106, there are another acids stronger than the sulfuric acid and you can compare them by yourself in http://www.jenck.com/t-acidez.htm., obviusly triflic acid is much stronger than the sulfuric one.Now, the strongest acid I know is the triflic acid, and be very carefull with the chlorosulfonic acid when you work in the laboratory, it burns¡¡¡¡¡I almost forgot it, keep in mind that the acidity of one acid depends too on the solvent in which it is dissolved, if the solvent is polar or non polar affects the acidity, so,perhaps you will need to learn some about analitical chemistry to understand this.see also: http://en.wikipedia.org/wiki/Triflic_acidI hope this helps
