Chemistry - Redox Reactions Question with Solution | TestHub

In$\left(\text{a}\right),$$\left(\text{b}\right)$and$\left(\text{d}\right);$Sulphur, nitrogen and Mn are in their maximum oxidation state, so they can only be reduced and thus can act only as oxidising agent.

$\left(\text{c}\right)$only${\text{H}}_2{\text{O}}_2$will act as both.

(i) In case of oxidising agent

${\text{H}}_2{\text{O}}_2$itself get reduced:

e.g.,

(ii) In case of reducing agent${\text{H}}_2{\text{O}}_2$itself get oxidise
