Which salt solution can generally show acidic nature in water?
Answer and explanation
Correct answer: Ammonium chloride
The governing idea is hydrolysis of ions from a weak base and a strong acid. Ammonium chloride is formed from hydrochloric acid, a strong acid, and ammonia or ammonium hydroxide, a weak base. In water, ammonium ions hydrolyse and release hydrogen ions, making the solution acidic. Sodium chloride is generally neutral, sodium carbonate is basic, and potassium sulphate is not the expected acidic salt in this school-level comparison.
