JEE Main2016ChemistryCoordination CompoundsActual
Which one of the following complexes will consume more equivalents of aqueous solution of AgNO 3 ?
Options
- AN a 2 C r C l 5 H 2 O
- BN a 3 C r C l 6
- CC r H 2 O 5 C l C l 2
- DC r H 2 O 6 C l 3
Correct answer
D. C r H 2 O 6 C l 3
Step-by-step solution
The number of ions will be precipitated only which are out of coordination sphere in given complexes. [ Cr ( H 2 O ) 6 ] Cl 3 ( aq )      ⇄     [ Cr ( H 2 O ) 6 ] 3 + ( aq )    +  3 Cl − ( aq ) 3 Ag +    +    3 Cl −    → 3 AgCl ↓    ( White ) More Equivalents of A g N O 3 aqueous solution will be consumed by more C l - ions given by the complex C l - a q + A g N O 3 → A g C
