Why is slaked lime added to acidic soil?
Answer and explanation
Correct answer: To reduce soil acidity
Acidic soil has a pH lower than the range suitable for many crops. Slaked lime, calcium hydroxide, Ca(OH)₂, is a basic substance. It reacts with excess acidic substances in the soil and neutralises them, thereby raising the soil pH toward a more suitable value. It is not added to create gas or sugar, and it does not increase acidity. Thus option A correctly states its agricultural purpose.
