Question

The questions below are related to the manufacture of ammonia

Ammonia can act as a reducing agent-write a relevant equation for such a reaction.

Answer 1

1. Ammonia($\mathit{N}{\mathit{H}}_{\mathbf{3}}$) is a good reducing agent since it can oxidize easily.
2. Ammonia contains lone pair of electrons in the Nitrogen atom which can be easily donated and act as a reducing agent.
3. Ammonia act as a reducing agent in the reaction with Copper oxide$\mathit{C}\mathit{u}\mathit{O}$, in which the Copper that is present in the $+2$ oxidation state gets converted to its zero oxidation state by the reaction with Ammonia.
4. The equation for this reaction is,

$\underset{Ammonia}{2N{H}_3\left(g\right)}+\underset{Copperoxide}{3CuO\left(s\right)}\to \underset{Copper}{3Cu\left(s\right)}+3H_{2}O\left(l\right)+\underset{Nitrogen}{N_2\left(g\right)}$
