Question

Why calcium hydroxide should not be added along with ammonium salts?​

Answer 1

Answer 2

Explanation -

Calcium hydroxide should not be added along with the ammonium slats because -

• Calcium hydroxide is alkaline in nature that affects the ph of the soil.
• Ammonium salts are generally used in the form of fertilizers to enhance plant growth and development.
• When ammonium salts react with calcium hydroxide, the chemical reaction leads to the formation of ammonia gas along with the calcium salt.

            $Ca(OH)_2 + Ammonium salt$ → $Calcium salt + NH_3 + H_2O$  

• The gas formed accumulated in the soil and reduces the efficiency of the fertilizer.
• The ammonia leads to less absorption of the nitrogen by the soil needed for plant growth.
• This leads to several diseases in plants due to the deficiency of nitrogen in the plant body.
