Question
Chapter 15, Problem 83CP
Interpretation Introduction
Interpretation: To balance the equation for the reaction that takes place in basic solution.
Concept introduction: Here are the rules to
Determine the oxidation numbers of the elements and write the oxidation and reduction half equation.
Balance the atoms of elements other than O and H. Use H2O to balance O, OH- to balance the charges. Equalize the number of electrons on both the half reactions and then add the half reactions.
