The compound `[CoCl_(3)I(C_(5)H_(5)N)_(2)] Br` will show the chemical test for which of the following ions? .A. `Br^(-)`B. `Cl^(-)`C. `I^(-)`D. `Br^(-)` as well as `Cl^(-)`

Answer» Correct Answer - A
The compound ionises as
`[CoCl_(3)I(C_(5)H_(5)N)_(2)]Br rarr [CoCl_(3)I(C_(5)H_(5)N)_(2)]^(+) + Br^(-)`
Hence, it easily gives the test for `Br^(-)` ions.
