The oxidation number of sulphur in `H_(2)S_(2)O_(7)` and iron in `K_(4)Fe(CN)_(6)` is respectively

A

`+ 6 and + 2`

B

`+ 2 and + 2`

C

`+ 8 and + 2`

D

`+ 6 and + 4`

Text Solution

Verified by Experts

The correct Answer is:
A
`H_(2)overset("*")S_(2) O_7`
`2 xx (+1) + 2 xx "x" + 7 xx (-2) =0`
`+2 + 2x -14 =0 implies 2x =14-2 =12`
`x =12/2 =+6 ` for S
`K_4 Fe(CN)_6`
`4 xx(+1) x + 6 xx (-1) =0 implies 4 + x -6 =0`
`x = 6 - 4 = +2` for Fe
