Which substance is most suitable for treating acidic soil?
Answer and explanation
Correct answer: Lime
Acidic soil contains an excess of acidic substances and therefore needs a basic material for correction. Lime, commonly containing calcium compounds such as calcium oxide or calcium hydroxide, reacts with and neutralises the excess acidity. Vinegar, lemon juice, and tamarind water are acidic, so they would increase rather than reduce soil acidity. Hence, option C is the most suitable treatment.
