Question

What happens when ammonia is treated with excess of chlorine?

Answer 1

When ammonia (NH₃) is treated with excess chlorine (Cl₂), the following reaction occurs:

\[\ce{NH3 + 3Cl2 -> NCl3 + 3HCl}\]

This reaction produces nitrogen trichloride (NCl₃). It is a highly explosive and volatile compound along with hydrochloric acid.
