An aqueous solution of a mixture contains `Br^(-)` and `I^(-)` ions. On passing `Cl_(2)` gas and adding `CHCl_(3)`, then organic layer will acquire :

A

violet colour

B

reddish brown colour

C

colourless

D

blue colour

Text Solution

Verified by Experts

The correct Answer is:
A

Violet colour will appear in `CS_(2)` layer. It is due to `I^(-)` ions. The violet colour masks the orange colour of `Br^(-)` ions.
