Which one of the following complexes will consume more equivalents of aqueous solution of AgNO3 ?
(a) Na2 [CrCl5 (H2O)]
(b) Na3 [CrCl6 ]
(c) [Cr(H2O)5Cl]Cl2
(d) [Cr(H2O)6 ]Cl3
Correct option: (d) [Cr(H2O)6 ]Cl3
Explanation:
More equivalents of AgNO3 aqueous solution will be consumed if complex will furnish more Cl– ions in solution. Hence complex [Cr(H2O)6 ]Cl3 will consume more equivalents of aqueous solution of AgNO3 .
