Complex salt can be made by the combination of `[Co^(III)(NH_3)_5Cl]^(x)` with

A

`PO_4^(3-)`

B

`Cl^-`

C

`2Cl^-`

D

`2K^+`

Text Solution

Verified by Experts

The correct Answer is:
C
`[Co^(III) (NH_3)_5 Cl]^X`
Charge on this cation `X = 3+5(0) - 1 = +2 `
Hence to balance the positive charge, 2 negative charge is required i.e. `2Cl^-`.
