Answer the following.
Give two reactions showing the oxidising property of concentrated H2SO4.
Answer the following.
Give two chemical reactions to explain oxidizing property of concentrated H2SO4.
Solution
Metals and nonmetals both are oxidized by hot, concentrated sulfuric acid which itself gets reduced to SO2.
- \[\ce{\underset{Copper}{Cu} + \underset{\underset{acid (Conc.)}{Sulfuric}}{2H2SO4} -> \underset{\underset{sulphate}{Copper}}{CuSO4} + \underset{\underset{dioxide}{Sulfur}}{SO2} + 2H2O}\]
- \[\ce{\underset{Sulphuric}{S} + \underset{\underset{acid (Conc.)}{Sulfuric}}{2H2SO4} -> \underset{\underset{dioxide}{Sulfur}}{3SO2} + 2H2O}\]
