On addition of conc. H(2)SO(4) to a chlo...

On addition of conc. `H_(2)SO_(4)` to a chloride salt, colourless fumes are evolved but in case of iodide salt, violet fumes come out. This is because

A

`H_(2)SO_(4)` reduces HI to `I_(2)`

B

HI is of violet colour

C

HI gets oxidised to `I_(2)`

D

HI changes to `HIO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
HI being a stronger reducing agent than `H_(2)SO_(4)`, reduces `H_(2)SO_(4)` to `SO_(2)` and is itself oxidised to `I_(2)`.
