Question

Complete and balance the following equation.

$\mathrm{S}+6{\mathrm{HNO}}_3\to \mathrm{\_\_\_\_\_}+\mathrm{\_\_\_\_\_\_}+\mathrm{\_\_\_\_\_}$

Answer 1

Oxidizing property of Nitric acid:

Action on non-metals: Nitric acid on reaction with non-metals like Sulphur produces Sulfuric acid, water and ${\mathrm{HNO}}_3$reduced to Nitrogen dioxide(${\mathrm{NO}}_2$).

$\mathrm{S}\left(\mathrm{s}\right)+6{\mathrm{HNO}}_3\left(\mathrm{aq}\right)\to {\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+6{\mathrm{NO}}_2\left(\mathrm{g}\right)$
