Question

What is Salt Hydrolysis ? How will you say that CUSO4 is a acidic salt​

Answer 1

Answer:

A salt is an ionic compound that is formed when an acid and a base neutralize each other. Salt hydrolysis is a reaction in which one of the ions from a salt reacts with water, forming either an acidic or basic solution.

Copper sulphate hydrolyse in water to give cupric hydroxide which is weak base and sulphuric acid which is strong acid. So hydrogen ion is more than hydroxyl ion in water.As a result the solution is acidic.

Copper sulphate is a salt of a strong acid, H2SO4, and a weak base, Cu(OH)2.

So, in aqueous solution, the Cu2+ ions undergo hydrolysis as follows:

Cu(2+) + H2O = CuOH(+) + H(+)

The release of H+ ions by hydrolysis makes the solution distinctly acidic.
