# Making Hydrochloric acid + Halogen Chemistry.

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

The melting point can be brought down to 600C by adding CaCl2 and the electrolysis will still only effect the NaCl since it is easier to separate. 600C, piece of cake. Just aman

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

50 molarity (concentration) of HCL would be very stong

with a pH of -1.699

thats a very good question! and one I dont actualy know the answer too, but in my experience of the practical uses of these acids, Ide 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 dont the TRUE CHEMICAL answer to that

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.

cool, so based on that, what would be the strongest, any idea as Ide like to know as well now

sadly in one respect, though Ive done tons of theory, I have more parctical experience, so to me, if it has a replacable H+ ion

its and acid, and the one that disassociate the best would be the strongest IMO, Periodic acid seems to come tops, but of course theres a world of difference between practical and theory, so I maybe well wrong?

(Lithium Hydroxide "eats" glass too, thats Anionic though, still quite a mean little Hydroxide though!)

Ill make this a second post as its 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 its 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? )

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.

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?

##### Share on other sites

Chloric acid contains Oxygen, Hydrocloric doesnt

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

##### Share on other sites

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 its an Acid the scale goes from 0 to 14

##### Share on other sites

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

##### Share on other sites

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

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

##### Share on other sites

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.

Okay. Don't worry. I'll eventually get it ! thanx alot for your help

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.

I drunk some HCl once and it never did me any harm. It tasted very sour and left a horrid after taste that lasted all day. Mind you is was only 3 Molar.

lol, I did the same and nearly got fired for it for giving the plant forman very close to a heart attack when he saw me do it (I did win my £20 bet though) LOL

The HCl in your stomach is significantly more concentrated than typical, diluted HCl... it will still do some damage to your mouth and throat tho.

and teeth! take a cup of tea 4 sugars after it, puts the plaque back on in no time

Where can you buy HCI? Becides the internet.

From your stomach. Just take out something (drinking a lot of booze may help getting some out of it) and carefully distill the nice contents of your stomach. Surely you get some HCl.

Just the other week, after drinking a bit of Jack Daniels, I kind of burped and coughed at the same time. This resulted in a VERY corrosive mixture of stomach liquids purging up into my throat for a small amount of time. My throat was raw and killing me for days after that. Couldn't believe how much that hurt.

ya ive had that happen before
