Question

Give two chemical equation for the following:

1. Reactions of nitric acid with non-metals.

Answer 1

• Reaction of nitric acid with non-metal
• $$\begin{gathered} \underset{\mathrm{carbon}}{\underset{}{\mathrm{C}}}+\underset{\mathrm{Nitric}\mathrm{acid}}{\underset{}{4{\mathrm{HNO}}_3}}\to \underset{\mathrm{carbon}\mathrm{dioxide}}{\underset{}{{\mathrm{CO}}_2}}+\underset{\mathrm{water}}{\underset{}{2{\mathrm{H}}_2\mathrm{O}}}+\underset{\mathrm{nitrogen}\mathrm{dioxide}}{\underset{}{4{\mathrm{NO}}_2}} \\ \underset{\mathrm{sulphur}}{\underset{}{\mathrm{S}}}+\underset{\mathrm{nitric}\mathrm{acid}}{\underset{}{6{\mathrm{HNO}}_3}}\to \underset{\mathrm{sulphuric}\mathrm{acid}}{\underset{}{{\mathrm{H}}_2{\mathrm{SO}}_4}}+\underset{\mathrm{water}}{\underset{}{2{\mathrm{H}}_2\mathrm{O}}}+\underset{\mathrm{nitrogen}\mathrm{dioxide}}{\underset{}{6{\mathrm{NO}}_2}} \end{gathered}$$
• When nitric acid reacts with metals it produces water and nitrogen dioxide as a byproduct.
