When an aqueous solution of copper (II) sulphate is saturated with ammonia, the blue compound crystallises on evaporation. The formula of this blue compound is : a. [Cu(NH3)4]SO4⋅H2O[\text{Cu}(\text{NH}_3)_4]\text{SO}_4 \cdot \text{H}_2\text{O} (square planar) b. [Cu(NH3)4]SO4[\text{Cu}(\text{NH}_3)_4]\text{SO}_4 (Tetrahedral) c. [Cu(NH3)6]SO4[\text{Cu}(\text{NH}_3)_6]\text{SO}_4 (Octahedral) d. [Cu(SO4)(NH3)5][\text{Cu}(\text{SO}_4)(\text{NH}_3)_5] (Octahedral)
