Concept

Problem: A disproportionation  reaction is an oxidation-reduction reaction in which the same substance is oxidized and reduced. Complete and balance the following disproportionation reactions.MnO42-(aq)  →  MnO4-(aq) + MnO2(s)  (acidic  solution)

FREE Expert Solution

We are being asked to balance the given oxidation-reduction reaction. The reaction is under acidic conditionsWhen balancing redox reactions under acidic conditions, we will follow the following steps.

Step 1: Separate the whole reaction into two half-reactions

Step 2: Balance the non-hydrogen and non-oxygen elements first

Step 3: Balance oxygen by adding H2O to the side that needs oxygen (1 O: 1 H2O)

Step 4: Balance hydrogen by adding H+ to the side that needs hydrogen (1 H: 1 H+)
