Write the structures of (i) peroxomonosulphric acid and (ii) peroxodisulphuric acid and find out the oxidation number of sulphur in them.

Explanation

(i) `underset("O.N. of S = 2 (+1)+ 2 (-1) + 3 (-2) + x = 0 or x = +6")underset("Peroxomonosulphric acid"(H_(2)SO_(5)))(overset(+1)(H)-overset(-1)(O)-overset(-1)(O)-underset(underset(-2)(O))underset(||)overset(overset(-2)(O))overset(||)(S)-overset(-2)(O)-overset(-1)(H))`
(ii) `underset("O.N. of S = 2 (+1) + 2(-1) + 6(-2)+2x = 0 or x = +6")underset("Peroxodisulphuric acid"(H_(2)S_(2)O_(8)))(overset(+1)(H)-overset(-2)(O)-underset(underset(-2)(O))underset(||)overset(overset(-2)(O))overset(||)(S)-overset(-1)(O)-overset(-1)(O)-underset(underset(-2)(O))underset(||)overset(overset(-2)(O))overset(||)(S)-overset(-2)(O)-overset(+1)(H))`
