Which one of the following complexes will consume more equivalent of aqueous solution of `Ag(NO_(3))` ?

Options

A. `Na_2 [CrCl_5 (H_2 O)]`
B. `Na_3 [CrCl_6]`
C. `[Cr(H_2 O)_5Cl] Cl_2`
D. `[Cr(H_2 O)_6 ] Cl_3`

Answer

D

Explanation

More equivalents of `AgNO_3` aqueous solution will be consumed if complex will furnish more `Cl^(-)` ions in solution. Hence complex `[Cr(H_2 O)_6 ]Cl_3` will consume more equivalents of aqueous solution of `AgNO_3`
