Question

Write balanced chemical equation of action of hot and concentrated nitric acid on copper?

Answer 1

1. The chemical equation depicting action of hot and concentrated nitric acid on copper yield copper nitrate and can be written as :
2. $$\begin{gathered} \mathrm{Cu}+4{\mathrm{HNO}}_3\to \mathrm{Cu}{\left(\mathrm{NO}\right)}_3+2{\mathrm{NO}}_2+2{\mathrm{H}}_2\mathrm{O} \\ \left(\mathrm{copper}\right)(\mathrm{conc}.\mathrm{nitric}(\mathrm{copper}(\mathrm{nitrogen}(\mathrm{water}) \\ \mathrm{acid})\mathrm{nitrate})\mathrm{di}-\mathrm{oxide}) \end{gathered}$$
