When `CS_(2)` layer containing both `Br_(2) " and" I_(2) (2 : 1)` is shaken with excess of chlorine `(Cl_(2))` water, the violet colour due to `I_(2)` disappears and a pale yellow colour appears in the solution. The disappearance of violet colour and appearance of pale yellow colour is due to the formation of :

Options

A. `I_(3)^(-)` and `Br_(2)` respectively
B. `HIO_(3)` and `BrCI` respectively
C. `ICI` and `BrCI` respectively
D. `I^(-)` and `Br^(-)` respectively

Answer

B

Explanation

`Br_(2)uarr +CI_(2)uarr hArr 2BrCI` (pale yellow solution)
`3I^(-)+CI_(2) uarr I_(3)^(-) +2CI^(-)`
`I_(3)^(-)+8CI_(2)+9H_(2)O rarr 3IO_(3)^(-)+16CI^(-)+18H^(+)`
