Question

oxidation number of h2s2o8

structure

O O
|| ||
HO-S-O-O-S-OH
|| ||
O O
So,
2(1) of hydrogens +2x for sulphur +2(-1)of two oxygens in peroxide linkage +6(-2) for normal oxygens



2+2x+(-2)+(-12)=0
2+2x-14=0
2x-12=0
2x=12
x=12/2
x=6

Answer 1

Hey buddy here's your answer ☺☺

@@@@@@@@@@@@@@@@@@@@@

Peroxydisulfuric acid is a sulfur oxoacid with the chemical formula H2S2O8. It is also called Marshall's acid. In structural terms it can be written HO3SOOSO3H. It contains sulfur in its +6 oxidation state, but it also contains a peroxide group, which is why it appears to be in a higher oxidation state than sulfates.
