When CS(2) layer containing both Br(2) "...

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 :

A

`I_(3^(-)) " and" Br_(2)` respectively.

B

`HIO_(3)` and BrCl respectively.

C

Icl and BrCl respectively.

D

`I^(-) " and" Br^(-)` respectively.

Text Solution

Verified by Experts

The correct Answer is:
B
`5Cl_(2)+I_(2) +6H_(2)O to 2HIO_(3) ("colourless")+10HCl`
`Br_(2)+Cl_(2) hArr 2BrCl`(pale yellow)
