Question

Give reasons for the following
a) sulphuric acid gives an acid salt but hydrochloric acid does not
b) Dil.HCl is stronger than highly concentrated acetic acid

Answer 1

Explanation:

a.)Sulphuric acid is a strong acid and it gets completely ionized in aqueous solution. - Sulphuric acid on reaction with a base gives both acidic salts and normal salts.

while HCl being a monobasic acid is left with no hydrogen ions.

b.)In an acetic acid solution, there is a large number of undissociated CH3COOH molecules, and just a few H+ and CH3COO- ions. Hence, dilute HCl acid is stronger than highly concentrated acetic acid.
