(c) Copper sulphate on treatment with potassium iodide precipitates cuprous iodide (Cu2 I2 ), liberates iodine gas and also forms potassium sulphate.
The balanced chemical equations for the reactions are given below:
(a) $Na_2CO_3 + HCl → NaCl + NaHCO_3$
(b) $NaHCO_3 + HCl → NaCl + H_2O + CO_2$
(c) $2CuSO_4 + 4Kl →2K_2SO_4 + Cu_2I_2 + I_2$
