When chlorine water is added to an aqueous solution of sodium iodide in the presence of chloroform, a violet colouration is obtained. On adding more of chlorine water and vigorous shakinh, the violet colour disappear. This shows the conversion of …….. into .......

A

`I_(2),HIO_(3)`

B

`I_(2),HI`

C

`HI,HiO_(3)`

D

`I_(2),HOI`

Text Solution

Verified by Experts

The correct Answer is:
A
`3CI_(2)+2NaI rarr 2NaCI+I_(2)`
`I_(2)` gives violet colouration in `C CI_(4)`.
`5CI_(2)+6H_(2)O+I_(2)rarr underset("Colourless")HIO_(3)+10HCI`
