Which salt solution is more likely to show acidic nature in water?
Answer and explanation
Correct answer: Ammonium chloride
Ammonium chloride is formed from hydrochloric acid, a strong acid, and ammonia, the weak base. In water, the ammonium ion hydrolyses and produces hydronium ions, so the solution is acidic: NH₄⁺ + H₂O ⇌ NH₃ + H₃O⁺. Sodium carbonate is generally basic, while sodium chloride and potassium nitrate are salts of strong acids and strong bases and are approximately neutral.
