1.	A co-ordination complex has the formula `PtCl_(4).2KCl`. Electrical conductance measurements indicate the presence of three ion in one formula unit. Treatment with `AgNO_(3)` produces no precipitate of `AgCl`. What is the co-ordination number of Pt in this complex ?A. 5B. 6C. 4D. 3
Answer» Correct Answer - B `PtCl_(4).2KCl-=K_(2)[PtCl_(6)]overset(aq.)iff2K^(+)+[PtCl_(6)]^(2-)`. So, it has three ions per formula unit. The `Cl^(-)` is present in coordination sphere so it will not given white precipitate with silver nitrate solution. So in the compounds the coordination number of platinum is 6.
