Adding lime to acidic soil is based on which principle?
Answer and explanation
Correct answer: Neutralisation
Acidic soil contains excess acidic substances that can harm plant growth. Lime, commonly calcium oxide, calcium hydroxide, or related carbonate material, is basic and reacts with the acids in the soil. This acid–base reaction reduces acidity and produces salt and water or related neutral products; the process is called neutralisation. Evaporation, condensation, and magnetisation do not involve an acid reacting with a base. Therefore, option A is correct.
