Question

Name two metals that react with very very dilute nitric acid.

Answer 1

• Magnesium reacts with very very dilute nitric acid and forms magnesium nitrate and hydrogen gas.

$\mathrm{Mg}+\underset{\underset{\mathrm{very}\mathrm{very}\mathrm{dilute}}{\mathrm{Nitric}\mathrm{acid}}}{2{\mathrm{HNO}}_3}\to \underset{\mathrm{Magnesium}\mathrm{nitrate}}{\mathrm{Mg}{\left({\mathrm{NO}}_3\right)}_2}+{\mathrm{H}}_2\left(\uparrow \right)$

• Manganese reacts with very very dilute nitric acid and forms manganese nitrate and hydrogen gas.

$\mathrm{Mn}+\underset{\underset{\mathrm{Very}\mathrm{very}\mathrm{dilute}}{\mathrm{Nitric}\mathrm{acid}}}{2{\mathrm{HNO}}_3}\to \underset{\mathrm{Manganese}\mathrm{nitrate}}{\mathrm{Mn}{\left({\mathrm{NO}}_3\right)}_2}+{\mathrm{H}}_2\left(\uparrow \right)$

Hence, Magnesium and manganese react with very very dilute nitric acid.
