(h) Choose the correct property (A), (B), (C) or (D) of Sulphuric acid for each of the
reactions (i) to (v):
(A) Oxidizing Agent
(B) Non-volatile
(C) Dehydrating Agent
(D) Acidic
(i) CuSO4.5H20 / Conc. → CuSO4 + 5H2O
H2SO4
(ii) S + 2H2SO4 (conc.) → 3SO2 + 2H2O
(iii) NaNO3 + H2SO4 (conc.) - <200°C → NaHSO4 + HNO3
(iv) Mg + H2SO4 + MgSO4 + H2
(v) Zn + 2H2SO4 (conc.) → ZnSO4 + SO2 + 2H20
