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, 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 itself gets oxidised to `I_(2)`.
