The oxidation state of S-atoms in Caro'...

The oxidation state of S-atoms in Caro's and Marshall's acids are:

A

`+6,+6`

B

`+6,+4`

C

`+6,-6`

D

`+4,+6`

Text Solution

Verified by Experts

The correct Answer is:
A
Caro's acid `=H_(2)SO_(5)`
Marshell's acid `=H_(2)S_(2)O_(3)`
The oxidation state in both the acids is +6 each because oxidation state cannot be greater than the number of valence electrons.
