Balancing Oxidation-Reduction Equations

Question 6 • Foothill-B Period-Chemistry-26/27B

Equations can be balanced by using the half-reaction method. Which step should be completed immediately after finding the oxidation states of atoms?

Answer
A
inserting the coefficients
B
balancing the half reactions
C
identifying the half reactions
D
inspecting the number of atoms

Explanation

After determining oxidation states, identify which atoms are oxidized and which are reduced. This lets you separate the overall equation into the oxidation and reduction half-reactions; balancing those half-reactions comes afterward. So the next step is identifying the half reactions.
