Question

The soil in a field is highly acidic. List any two materials which can be added to the soil giving specific reason.

Answer 1

sodium carbonate can be added to acidic soil to reduce its acidity

Answer 2

In highly acidic field, we need to neutralize that acidic nature with bases to form salts and water which make the field safe from acidic nature.

Mainly For neutralization , We can apply bases like Calcium oxide(CaO - Quicklime), Calcium hydroxide(Ca(OH)2 - Slaked lime) , Calcium carbonate ( CaCO3 - Lime stone) and Basic form of Magnesium Carbonate (MgCO3 - Magnesia alba ).

Reason - * These bases can destroy acids and they also be destroyed in neutralization process. This reaction leads to formation of Salts and water.

* These types of bases are used in the fields which suffer from

acidic rains and due to excessive usage of acidic fertilizers.

But, Excessive use of these bases results in basicity of field
