Question

Which of the following statements is not correct?

Moderate

A

The oxidation number of S in ${({NH}_{4})}_{2} S_{2} O_{8}$ is +6
B

The oxidation number of Os in ${OsO}_{4}$ is +8
C

The oxidation number of S in $H_{2} {SO}_{5}$ is +8
D

The oxidation number of O in KO₂ is -1/2

Solution

$(1) {(\overset{+ 1}{{NH}_{4}})}_{2} S_{2} {O_{8}}^{2 -} ∴ Oxidation state of S = \pm 6 (Since S_{2} {O_{8}}^{2 -} has one peroxide bond) (2) Oxidation state of Os = + 8 (3) Oxidation state of S in H_{2} {SO}_{5} = + 6 (Since it has one peroxide bond) (4) K^{1 +} {O_{2}}^{1 -}, oxidation state of O = - 1 / 2$
