Question

Complete the following chemical reaction and classify into (a) hydrolysis, (b) redox and (c) hydration reactions.
$M n O_{4}^{-} (a q) + H_{2} O_{2} (a q) \to$

Open in App

Solution

The complete chemical equation is given below:
$M n O_{4}^{-} (a q) + 5 H_{2} O_{2} (a q) + 6 H^{+} \to 2 M n^{2 +} (a q) + 8 H_{2} O (l) + 5 O_{2} (g)$

In this reaction, Mn is reduced and $H_{2} O_{2}$ is oxidized. Both oxidation and reduction occur in the same reaction.

So this is an example of a redox reaction.
