One mole of the complex ` CoCl_(3) . 6 H_(2) O` on reaction with excess of ` AgNO_(3) ` agives two moles of white precipitate thus , complex is

A

` [Co (H_(2) O) _(6) ]Cl_(3) `

B

`[Co (H_(2) O)_(5) Cl ]Cl_(2) .H_(2) O `

C

`[Co (H_(2) O) _(4)Cl_(2) ]Cl.2H_(2) O`

D

`[Co(H_(2)O)_(3) Cl_(3)].3H_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
B
`CoCl_(3) .6H_(2) O +AgNO_(3)to 2"mole of " AgCl`
thus two Cl-atoms are outside the coordination sphere
`C.N " of" Co=6`
thus , `[Co(H_(2)O)_(5)Cl]Cl_(2).H_(2)O.`
