Question

what is oxidation state of sulphur in sulphuric acid and sulphur dioxide?​

Answer 1

Answer:

Acid Formula Oxidation number

Sulfuric acid H2SO4 +6

Polysulfuric acids including disulfuric acid or pyrosulfuric acid H2SO4·nSO3 +6

Peroxymonosulfuric acid H2SO5 +6

Explanation:

Charge on hydrogen is +1 and charge on oxygen atom is -2.Total charge on H

2

SO

4

is 0.

Let the oxidation state of sulphur be x

∴2(+1)+x+4(−2)=0

∴x−6=0

∴x=+6

Therefore, the oxidation number of sulphur in H

2

SO

4

in +6.
