On addition of con. H(2)SO(4) to a chlor...

On addition of con. `H_(2)SO_(4)` to a chloride salt, colourless 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 oxides to `I_(2)`

D

HI changes to `HIO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
In case of chloride salt, HCl(g) is evolved. In case of iodide salt, Hl evolved is oxidised to `l_(2)` since it is a powerful reducing agent.
