Ammonium sulfate, being derived from a strong acid and a weak base, contributes to soil acidity when dissolved in water.

1. Correct
2. Incorrect
3. Not enough information
4. Not applicable

Correct answer: Correct

Solution

Ammonium sulphate is a salt of a weak base (ammonium hydroxide) and a strong acid (sulphuric acid). In aqueous solution, it hydrolyzes to release H+ ions, increasing acidity.
