0.1 M solution of which one of these substances will react basic ? — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

Sodium borate is a salt of weak acid and strong base. Therefore, its aqueous solution is strongly basic i.e. pH >7. Sodium sulphate consists of strong acid and strong base hence its aqueous solution will be neutral i.e. pH=7. Calcium nitrate consists of strong acid and strong base hence its aqueous solution will be neutral i.e. pH=7. Ammonium chloride is salt of weak base and strong acid; hence its aqueous solution will be strongly acidic i.e. pH<7. Solubility and Solubility Product
