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 l_(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:

Answer»

`I_(3)^(-)` and `Br_(2)` respectively<BR>`HIO_(3)` and `BrCl` resectively
`ICI` and `BrCl` respectively
`I^(-)` and `Br^(-)` respectively

Solution :`5Cl_(2)+l_(2)+6H_(2)O to 2HIO_(3) ("COLOURLESS") +10HCl`
`Br_(2)+Cl_(2) hArr 2BrCl` (pale YELLOW)
