A salt solution reacts with some drops of chloroform and the mixture is shaken with chlorine water. The chloroform layer becomes violet. Salt solution contains:

A

`NO_2^(-)` ion

B

`NO_3^(-)` ion

C

`Br^(-)`

D

`I^(-)` ion

Text Solution

Verified by Experts

The correct Answer is:
D
`2Nal+Cl_2 rarr 2NaCl +I_2` (Dissolves in `CHCl_3` to give violet colour)
Chlorine displaces iodine from salt. The iodine get dissolve in `CHCl_3` or `CCl_4` to produce violet colour.
