Correct answer: (c) The oxidation number of S in H2SO5 is +8.
Explanation:
(a) \((\overset{+1}{N}H_4)_2S_2O_8^{2-}\)
∴ Oxidation state of S = +6
(Since S2O82- has one peroxide bond)
(b) Oxidation state of Os = +8
(c) Oxidation state of S in H2SO5 = +6
(Since it has one peroxide bond)
(d) K+1O21-, oxidation state of O = \(-\frac{1}{2}\)
