Problem

Complete and balance the following equations, and identify the oxidizing and reducing agents.

Part A

MnO4(aq) + CH3OH(aq) → Mn2+(aq) + HCO2H(aq) (acidic solution)

Express your answer as a chemical equation. Identify all of the phases in your answer.

Part B

oxidizing agent, reducing agent

Express your answers as chemical expressions separated by a comma.

Solution
  • Balance the redox reaction following a series of steps and determine the oxidizing/reducing agent in each reaction.
  • Recall that the oxidizing agent is the one being reduced (GER-OA = Gain electrons, reduced- Oxidizing agent) while reducing agent is the one being oxidized (LEO-RA = Lose electrons, oxidized – Reducing agent)

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+)
