The oxidation number of `S` in `H_(2)S_(2)O_(8)` is

A

`+2`

B

`+4`

C

`+6`

D

`+7`

Text Solution

Verified by Experts

The correct Answer is:
C
`H_(2)S_(2)O_(8)` is `{:(" O O"),(" || ||"),(H-O-S-O-O-S-OH),(" || ||"),(" O O"):}`
It contains peroxide linkage for which the oxidation number o these two oxygen atoms will be -1 each
`:. 2xx(+1)+2x+6xx(-2)+2xx(-1)=0`
or`2+2x-12-2=0or x=+6`.
