Question
The salt which will give an acidic solution on dissolving in water is:
(a) KCl
(b) NH4Cl
(c) Na2Co3
(d) CH3COONa
Solution
NH4Cl
NH4Cl is formed with a weak base, ammonium hydroxide (NH4OH), and a strong acid, hydrochloric acid (HCl). On dissolving in water, NH4Cl hydrolyses to form more H+ ions than OH- ions. Thus, it is acidic with a pH less than 7.
