On adding of conc. `H_(2)SO_(4)` ot a chloride salt colourless fumes are evolved but in case of iodide salt. Violet fumes come out. This is because

A

HI is of violet colour

B

HI gets oxidised to `I_(2)`

C

HI changes to `HIO_(3)`

D

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

Text Solution

Verified by Experts

HI gets oxidised to `I_(2).2I^(-)+H_(2)SO_(4) to SO_(4)^(2o+)+2HI,`
`H_(2)SO_(4) to H_(2)O+SO_(2)+(O), 2HI+O to H_(2)O +I_(2)`
