Question

Give a balanced equation by partial equation method, [steps are given below].

The reaction of excess ammonia with chlorine – Ammonia as a reducing agent

1. Ammonia first reacts with chlorine to give hydrogen chloride and nitrogen.
2. Hydrogen chloride then further reacts with excess ammonia to give ammonium chloride.

Answer 1

1. Ammonia reacts with chlorine to give hydrogen chloride and nitrogen.
2. Hydrogen chloride reacts with excess ammonia to give ammonium chloride.

2NH₃ + 3Cl₂ → 6HCl + N₂ 
6NH₃ + 6HCl → 6NH₄Cl   
8NH₃ + 3Cl₂ → 6NH₄Cl + N₂
