Explanation:
When a salt is dissolved in water, the solution could be acidic, basic or neutral depending on the nature of acid and base from which the salt was formed.
When a salt is formed from a strong acid and a weak base, the salt solution is acidic.
For instance, NH4Cl is a salt formed from NH3 which is a weak base and HCl which is a strong acid. The salt hydrolyses as follows;
NH4^+(aq) + H2O(l) ------> H3O^+(aq) + NH3(aq)
Hence an acidic solution is formed.
