One of the following salt will give an alkaline solution on dissolving in water. This is:(a) Na₂CO₃
(b) Na₂SO₄
(c) NaCl
(d) (NH₄)₂SO₄

Academic Chemistry NCERT Class 10

Correct Answer: (a) Na2CO3

Explanation: Na2CO₃ on dissolving in water forms NaOH (strong base) and H₂CO₃ (weak acid). Therefore, the solution becomes alkaline in nature.
