EAN of the central metal in the complexes :
K2[Ni(CN4].[Cu(NH3)4]SO4 and K2[PtCl6]
34, 35, 86
EAN of Ni in [Ni(CN)4]2– = 28 – 2(O.N) + 4 × 2 = 34;
EAN of Cu in (Cu(NH3)4]2+ = 29 – 2(O.N) + 4 × 2 = 35
EAN of Pt in [PtCl6]2– = 78 – 4(O.N) – 6 × 2 = 86.
0.001 mol of Co(NH3)5(NO3)(SO4) was passed through a cation exchanger and the acid coming out of it required 20 ml of 0.1 M NaOH for neutralization. Hence, the complex is
When H2S is passed through a cuperic salt added to excess of KCN, no black precipitate of CuS is obtained. This is due to the presence of copper largely as:
