(i) When conc. H2SO4 is added to a crystal of hydrated copper sulphate, it removes water of crystallisation from salt.

(ii) C12H22O11 + conc. H2SO4 6C + 6H2O

Solution 2014-1

(i) Dehydrating property of sulphuric acid:

H2SO4 has a great affinity for water, and therefore, it acts as a dehydrating agent.

 

(ii) Acidic nature of sulphuric acid:

It acts as a strong dibasic acid.

It reacts with metals, metal oxides, metal hydroxides and carbonates 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 

 

(iii) As a non-volatile acid: 

It has a high boiling point, so it is used to prepare volatile acids such as HCl, HNO3 and acetic acid from their salts.

NaCl + H2SO4 NaHSO4 + HCl

NaNO3 + H2SO4 NaHSO4 + HNO3

CH3COONa + H2SO4 NaHSO4 + CH3COOH

Solution 2015-1
