When crystals of `CuSO_(4)` are dissolved in water, there is hardly any evidence for the presence of `Cu^(2+)` ions or ammonia molecules. A new ion `[Cu(NH_(3))_(4)]^(2+)` is furnished in which ammonia molecules are directly linked with the metal ion . Similarly the aqueous solution of `Fe(CN)_(2).4KCN` does not give tests of `Fe^(2+)` and `CN^(-)` ions but gives test of a new ion, `[Fe(CN)_(6)]^(4-)` also called complex ions. 15. The hybrid state of `Cu[Cu(NH_(3))_(4)]^(2+)` isA. `sp^(3)`B. `sp^(3)`dC. `sp^(3)d^(2)`D. `dsp^(2)`
