Question

Dilute nitric acid is generally considered a typical acid accept for its reaction in metals.

In what way is dilute nitric acid different from other acids when it reacts with metals?

Answer 1

1. When dilute nitric acid (${\mathrm{HNO}}_3$) react with metals, this acid even oxidizes and hydrogen gas are produced during reaction.
2. When it react (${\mathrm{N}}_2\mathrm{O},\mathrm{NO}$) gas produced.
3. Nitric acid is act as an oxidizing agent.
4. Example : $$\begin{gathered} \mathrm{Fe}\left(\mathrm{s}\right)+{\mathrm{HNO}}_3\to \mathrm{Fe}{\left(\mathrm{NO}\right)}_3\left(\mathrm{s}\right)+\mathrm{NO}\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right) \\ \left(\mathrm{Iron}\right)(\mathrm{nitric}(\mathrm{Ferric}(\mathrm{nitric}(\mathrm{water}) \\ \mathrm{acid})\mathrm{nitrite})\mathrm{oxide}) \end{gathered}$$
