Question

`(I) K_(3)[Co(CN)_(6)]+[Cr(NH_(3))_(6)]Cl_(3)overset("acetone ")tox+3KCldarr`
`K_(3)[Cr(CN)_(6)]+[Co(NH_(3))_(6)]Cloverset("Acetone")toy+3KCldarr`
the solution was filted x and y are obtained after evoporation of the solvent from the filtrate.
when y is sent through anion exchange resn , then the complex eluted is
A. `[Co(NH_(3))_(6)]^(3+)`
B. `[Cr(NH_(3))_(6)]^(3+)`
C. `[Cr(NH_(3))_(6)]^(3-)`
D. `[Cr(CN)_(6)]^(3-)`

Answer 1

Correct Answer - a
`x: [Cr (NH_(3))_(6)][Co(CN)_(6)] : y [Co(NH_(3))_(6)][Cr(CN)_(6)]`
