Question

Some properties of sulphuric acid are listed below. Choose the role played by sulphuric acid as A, B, C or D which is responsible for the reactions (i) to (v). Some role/s may be repeated.

1. Dilute acid
2. Dehydrating agent
3. Non-volatile acid
4. Oxidising agent
   1. \[\ce{CuSO4 * 5H2O ->[conc H2SO4] CuSO + 5H2O}\]
   2. \[\ce{S + 2H2SO4 [conc] -> 3SO2 + 2H2O}\]
   3. \[\ce{NaNO3 + \underset{[conc]}{H2SO4} ->[<200^\circ C] NaHSO4 + HNO3}\]
   4. \[\ce{MgO + H2SO4 -> MgSO4 + H2O}\]
   5. \[\ce{Zn + 2H2SO4 [conc] -> ZnSO4 + SO2 + 2H2O}\]
