Question

Explain the effects of NH3 (aq) and HCl (aq) on the CuSO4 solution in terms of Le Chatelier's principle.

Answer 1

CuSO4 solution with ammonia give more soluble complex . that means in presence of NH3 , CuSO4 solubility increases

CuSO4 (aq) + NH3 (aq) --------------------> [ Cu (NH3)4 ] SO4 (aq)

( more soluble complex )

CuSO4 when mix with HCl solution there is no significant react takes place .

one can may expect the reaction between CuSO4 and HCl is written below . but nothing happens in the mixture this reaction is not correct . it is doesnot takes palce

CuSO4(aq) + HCl(aq) ----------------> CuCl2(aq) + H2SO4(aq)
