Question

In the following reaction:
$M n O_{2} (s) + 4 H C l (a q) \to M n C l_{2} (a q) + C l_{2} (g) + 2 H_{2} O (l)$
Identify the oxidising and reducing agents.

Solution

$M n O_{2}$ loses oxygen therefore it is reduced and thus it acts as an oxidizing agent. On the other hand HCl loses hydrogen. It is oxidized thus it acts as a reducing agent.Therefore in the reaction $M n O_{2}$ is the oxidizing agent and HCl is the reducing agent.
