Match the action of $\mathrm{H}_{2} \mathrm{O}_{2}$, in aqueous medium given in column A with the oxidation/reduction listed in column B | A: action of $\mathrm{H_2O_2}$ | B: type of reaction |
|---|
| (1) Oxidation in acid | (A) $[\mathrm{Fe(CN)_6}]^{3-} \rightarrow [\mathrm{Fe(CN)_6}]^{4-}$ |
| (II) Oxidation in base | (B) $[\mathrm{Fe(CN)_6}]^{4-} \rightarrow [\mathrm{Fe(CN)_6}]^{3-}$ |
| (III) Reduction in acid | (C) $\mathrm{MnO_4^{-}} \rightarrow \mathrm{Mn^{2+}}$ |
| (IV) Reduction in base | (D) $\mathrm{Mn^{2+}} \rightarrow \mathrm{Mn^{4+}}$ |
(a)$\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]^{3-} \rightarrow\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]^{4-}$ (II) Oxidation in base
(b)$[\mathrm{Fe}(\mathrm{CN}) 6] 4-\rightarrow\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]_{3-}$ (III) Reduction in acid
(c)$\mathrm{MnO}^{4-} \rightarrow \mathrm{Mn}^{2+}$ (IV) Reduction in base
(d)$\mathrm{Mn}^{2+} \rightarrow \mathrm{Mn}^{4+}$
