How acidic is hydrochloric acid?

Answer 1

Hydrochloric acid is a strong acid, which means it dissociates completely in solution. You can not be more ' acidic ' than that.

Just because an acid ionizes completely doesn't really say how acidic

a solution of HCl will be. HCl is defined as a strong acid because it

ionizes completely. However, if its diluted enough one can drink it just

like vinegar (about a 5% solution of acetic acid). Of course one could

dilute it enough to make it so the solution is pretty much no more

acidic than pure water.

The original answer was probably answering what was the intent

of the question, whether HCl is a strong or weak acid.

Answer 2

It depends on the concentration of the HCl. A 5% solution will have a different density than a 25% solution.

Answer 3

Hydrochloric acid is not "poisonous" because it is neither toxic or a venom. Instead, hydrochloric acid is corrosive, though how corrosive it is depends on the concentration.
