उत्तर
Acidic nature of sulphuric acid:
It acts as a strong dibasic acid.
H2SO4 → 2Hi+ + SO42-
It reacts with metals, metal oxides, metal hydroxides, carbonates etc. to form metallic sulphates and hydrogen at ordinary temperature.
Mg + H2SO4 → MgSO4 + H2 ↑
CuO + H2SO4 → CuSO4 + H2O
2NaOH + H2SO4 → Na2SO4 + 2H2O
ZnCO3 + H2SO4 → ZnSO4 + H2O + CO2 ↑
