Question

Under what soil condition do you think a farmer would treat the soil of his fields with quicklime (calcium oxide) or slaked lime (calcium hydroxide) or chalk (calcium carbonate)?

Answer 1

Treatment of soil:

1. If the soil is acidic and unsuitable for farming, the farmer can neutralise the acidity with slaked lime, quick lime and chalk.
2. Farmers typically use slaked lime, quick lime and chalk to boost fertility.
3. They also use these bases when the soil becomes too acidic for a variety of reasons.
4. These bases act as a neutralising agent, removing the acidity from the soil.
5. It will be a neutralising reaction in this case.
