A farmer noticed that his field soil was too acidic, which was harming his crops. Which of the following substances should he add to his soil to neutralize its acidity?
Options
Option A
Vinegar
Option B
Lemon juice
Option C is correct
Slaked lime (Calcium hydroxide)
Option D
Common salt
Explanation
To neutralize acidic soil, a basic substance needs to be added. Slaked lime, which is calcium hydroxide, is a basic compound commonly used to reduce the acidity of soil. Vinegar and lemon juice are acidic and would increase the soil's acidity. Common salt is a neutral substance and would not effectively neutralize the acidity.
