Which of the following gives the maximum number of ions in aqueous solution?

Step-by-step solution

PtCl ₄ 6 NH ₃ [hexammine platinum (IV) chloride]. It gives 4 Cl ⁻ ions and 6 NH ₃ , not involved in its ion because NH ₃ are present out of the complex of PtCl ₄ . aligned & Hence, PtCl ₄ 6 NH ₃ [ Pt ( NH ₃ )₆ ] Cl ₄ & [ Pt ( NH ₃ )₆ ]⁴⁺+4 Cl ⁻ _ Total 5 ions & aligned In Ni ( CO )₄, CO is very strong binding ligand, it is difficult to remove all 4 CO from nickel. On other hand, CoCl ₃ 5 H ₂ O dissociates into Co ³⁺ , 3 Cl ⁻ ions and 5 H ₂ O molecules. Hence, only PtCl ₄ 6 NH ₃ gives maximum number of ions in aqueo
