I suppose its considered cheating to use a strong acid to create one.

[YT2095]

well it really all depends on what you want it for realy, perchloric acid does have its uses, and if you have an abundance of H2SO4 and a perchlorate salt, it`s the easiest way to go.
but`s it darn nasty stuff!
most reactions that require a perchlorate salt are best done without making the acid, simple displacement and fractional re-crystalisation`s usualy the best/safest bet :)

OMG HCl IS A DANGEROUS CHEMICAL PEOPLE CAN SEVERLY BURN THEIR SKIN AND KILL THEMSELVES IF THEY DRINK IT, WE'VE GOTTA HIDE THIS INFORMATION FROM THE PUBLIC IT'S DEADLY!!!!!!

Don't mind me, I'm taking a break on a all nighter.

Hold up no, why not just take bleach boil to retrain NaCl crystals add water to amount of molarity then use Hydrogen either from a mazz pump or bottled. Im not telling you to do this it can be very dangerous if you dont know what you are doing AND SHOULD ONLY BE DONE IN A FUMEHOOD>, as the reaction may give off chlorine gas which can be deadly. Or try making Sulphuric acid using molten sulphur flowers.

[YT2095]

Hmmm.. your intentions are admirable, but a few points first :)
boiling "bleach" or "Chlor-ox" (same stuff) will indeed leave you with some naCl (house salt) and also a little NaClO3 (Sodium Chlorate). adding Hydrogen would not in anway react at standard RTP.

Powdered Sulpher (flower of Sulpher) would have to be a multi-stage reaction, 1`stly would require you burn it in Oxygen to make Sulpher Dioxide, then further heating with Oxygen over a catalyst to make Sulpher TRIoxide, this would then have to be added to pre existing conc sulphuric acid to make Oleum, the subsequently added to water to match the correct molarity required.
it`s cheaper to just buy the stuff pre-made :)

 

you`re thinking along the right lines though ;)

 

[aommaster]

Well YT, what is the top strongest acid then. I wouldn't like to be near it !

[wolfson]

Well it all depends on molarity (hydrogen ion concentration).

50 molarity (concentration) of HCL would be very stong

with a pH of -1.699

[YT2095]

thats a very good question! and one I don`t actualy know the answer too, but in my experience of the practical uses of these acids, I`de have to say Periodic acid would be tops, followed by Sulphuric and then Perchloric acid, although Nitric acid is my favorite of all (how Nerdy does that sound! LOL).
I think someone else had better answer this though, as I really don`t the TRUE CHEMICAL answer to that :)

[wolfson]

The strength of an acid is determined by its degree of
dissociation. Complete dissociation of an acid molecule
means that all of the H+ (hydrogen ions) are free and able to
react. Hydrochloric acid (HCl) is one acid that dissociates completely in H20 and is considered one of the strongest acids. Hydrofluoric acid (HF) is often considered stronger because the fumes that it releases are very toxic and it has the ability to dissolve glass, but technically it is a weak acid because it does not
dissociate as completely as HCl.

[YT2095]

cool, so based on that, what would be the strongest, any idea as I`de like to know as well now :)

sadly in one respect, though I`ve done tons of theory, I have more parctical experience, so to me, if it has a replacable H+ ion
it`s and acid, and the one that disassociate the best would be the strongest IMO, Periodic acid seems to come tops, but of course there`s a world of difference between practical and theory, so I maybe well wrong?

(Lithium Hydroxide "eats" glass too, that`s Anionic though, still quite a mean little Hydroxide though!) :)

[YT2095]

I`ll make this a second post as it`s better kept seperate for clarity.

Aom, Also, do NOT confuse acid strength with Concentration!
it has nothing at all to do with it :)
if I have 100% pure acid (any acid will do) and it`s PH is 3, then I pour that acid into and equal volume of pure water, the acid concentration will be 50% but the PH will still be 3 (so it will be just as STRONG).

hope that makes some kind of sense? :))

[wolfson]

The Guiness Book of Worls Records in 1957 named these are the top acid (starting strongest first:

HClO4, HCl, H2SO4, then HNO3

But i am nearly 100% sure that H(CB11H6Cl6) is the strongest acid at this time.

[YT2095]

3 outa 4 aint bad :)

[aommaster]

Whoa. U guys REALLY know alot. Thanx. And i always thought that hydrofluoric was dangerous!
Ok, some other stuff, what does amalgam look like, i know i asked it before, but it got removed.
And, what is the difference between chloric and hydrochloric acid?

[YT2095]

Chloric acid contains Oxygen, Hydrocloric doesn`t :)

[aommaster]

Is there a difference in their pH? And what does it stand for anyway (pH)?

[YT2095]

there would be a difference in their PH yes, PH stands for Potential Hydrogen.

ph 7 is neutral like water, above 7 it is Alkaline below 7 it`s an Acid the scale goes from 0 to 14 :)

[aommaster]

This is related to the free H+ ions moving about in the solution, right?Is this similar to water potential, only with Hydrogen ions?

[YT2095]

I have no idea if it is or not, as I`m unfamiliar with the term "Water Potential"

but yes, the +H ions is what it`s all about :)

[wolfson]

The water potential know as Kw = the water constant which is 1.0e-14, the concentration of hydrogen ions. You only use the Kw when calculating the pH of bases (OH), Acids are substances that form hydrogen ions so you dont need to include Kw. So the pH is the hydrogen ion concentration, Anti-log pH value gives you the hydrogen ion concentration, i.e if you have 0.0258 M (molarity), of Hydrochloric acid (HCL), then the pH would be, pH = -log(0.0258) = 1.588 = pH 1.588 (strong acid). And if you had a 0.0258 M of Sodium Hydroxide (NaOH, Note the OH), then the pH would be, = 0.0258 / 1.0e-14 (Kw) = 2.58e12 then, log(2.58e12) note no - on log, = pH 12.41 (strong base), hope you got that.
