We’re being asked to complete the following sentence:

The following is a(n) ______ half-reaction in which ______ electrons are transferred.

Given Reaction:      ClO3 → ClO2

We’ll write and determine the half-reaction using the following steps:

Step 1: Balance the non-hydrogen and non-oxygen elements first
Step 2: Balance oxygen by adding H2O to the side that needs oxygen (1 O: 1 H2O)
Step 3: Balance hydrogen by adding H+ to the side that needs hydrogen (1 H: 1 H+)
Step 4: Balance the charges: add electrons to the more positive side (or less negative side)
Step 5: Determine if the reaction is oxidation half-reaction and the reduction half-reaction.
