प्रश्न
Concentrated sulphuric acid is both an oxidizing agent and a non-volatile acid. Write one equation each to illustrate the properties of sulphuric acid mentioned above.
उत्तर
As an Oxidizing agent :
H2SO4 → H2O + SO2 + [O]
C + 2[O] → CO2
As a non-volatile acid :
\[\ce{NaCl + H2SO4 ->[200°C] NaHSO4 + HCl}\]
