उत्तर
Metals and nonmetals both are oxidized by hot, concentrated sulfuric acid which itself gets reduced to SO2.
- \[\ce{\underset{Copper}{Cu} + \underset{\underset{acid (Conc.)}{Sulfuric}}{2H2SO4} -> \underset{\underset{sulphate}{Copper}}{CuSO4} + \underset{\underset{dioxide}{Sulfur}}{SO2} + 2H2O}\]
- \[\ce{\underset{Sulphuric}{S} + \underset{\underset{acid (Conc.)}{Sulfuric}}{2H2SO4} -> \underset{\underset{dioxide}{Sulfur}}{3SO2} + 2H2O}\]
