Question

Briefly describe how water reacts with Nitrogen dioxide stating the experimental condition and write the balanced chemical equations.

Answer 1

• Nitrogen dioxide, a non-metallic oxide, reacts with water to form nitric acid.
• This reaction takes place very easily in water.
• Therefore produced nitrogen dioxide gas is sent to water to manufacture nitric acid in the chemical industry.
• This reaction is a redox reaction which means it takes place between an oxidising substance and a reducing substance.
• The chemical reaction between nitrogen dioxide and water is:
• $\underset{\mathrm{nitrogen}\mathrm{dioxide}}{\underset{}{2{\mathrm{NO}}_2\left(\mathrm{g}\right)}}+\underset{\mathrm{water}}{\underset{}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}}\to \underset{\mathrm{Nitric}\mathrm{acid}}{\underset{}{{\mathrm{HNO}}_3\left(\mathrm{aq}\right)}}+\underset{\mathrm{Nitrous}\mathrm{acid}}{\underset{}{\mathrm{HNO}\left(\mathrm{aq}\right)}}$
