Question

In which of the following reactions $H_{2}O_{2}$ acts as a reducing agent ?
$\left(i\right)H_{2}O_{2}+2H^{+}+2e^{-} \rightarrow 2H_{2}O$
$\left(ii\right)H_{2}O_{2}-2e^{-} \rightarrow O_{2}+2H^{+}$
$\left(iii\right)H_{2}O_{2}+2e^{-} \rightarrow 2\left(OH\right)^{-}$
$\left(iv\right)H_{2}O_{2}+2\left(OH\right)^{-}-2e^{-} \rightarrow O_{2}+2H_{2}O$

• A. $\left(ii\right)$ and $\left(iv\right)$
• B. $\left(i\right)$ and $\left(ii\right)$
• C. $\left(iii\right)$ and $\left(iv\right)$
