Oxidation of thisulphate `(S_(2)O_(3)^(2-))` ion by iodine gives

A

`S_(4)O_(6)^(2-) +I^(-)`

B

`SO_(4)^(2-) + I^(-)`

C

`SO_(3) + I^(-)`

D

`S_(4)O_(6)^(2-) + I_(3)^(-)`

Text Solution

Verified by Experts

The correct Answer is:
A
`I_(2) + Na_(2)S_(2)O_(3) to 2NaL + Na_(2)S_(4)O_(6)`
`I_(2) + S_(2)O_(3)^(2-) to 2I^(-) + S_(4)O_(6)^(2-)`
