(b) Carbon

Answer

(a) Sulphuric acid behaves as a non volatile acid.

KNO3+H2SO4[conc.]→<200°CKHSO4+HNO3\text{KNO}_3 + \text{H}_2\text{SO}_4 [\text{conc.}]\xrightarrow{\lt 200 \degree\text{C}} \text{KHSO}_\text{4} + \text{HNO}_\bold{3}

(b) Sulphuric acid behaves as an oxidizing agent

C + 2H2SO4 ⟶ CO2 + 2H2O + 2SO2
