Question

Ammonia on small scale is obtained from

(a) ammonium salts which decompose when treated with caustic soda

(b) sodium salts which decompose when treated with caustic soda

(c) ammonium salts which decompose when treated with slaked lime

(d) sodium salts which decompose when treated with slaked lime​

Answer 1

Ammonium salts which decompose when treated with caustic soda.

Explanation:

• When ammonium salt is heated with a solution of caustic soda, ammonia gas is released.
• Caustic soda, also known as sodium hydroxide, is a strong base.
• It is often reacted with ammonium salts, such as ammonium chloride, and these reactions yield ammonia.
• Hence, option a is correct. ammonium salts which decompose when treated with caustic soda
