REDOX Half Reaction Method in Acidic Solutions -- STEPS
1) Using the given partial net ionic equation, write two ½ reactions.
Note that one is a reduction and one is an oxidation.
Also, all species present in the given equation must be included in one of the
half reactions.
2) Time to do some balancing. For each of the half reactions:
A) Balance all elements except H and O, by adding coefficients as necessary.
B) Balance O by adding H2O to either the reactant side or product side.
C) Balance H by adding H+ to either the reactant side or the product side.
D) Balance charge by adding e- to either the reactant side or the product side.
3) Multiply each ½ reaction by some whole number such that e- gained = e- lost.
4) Add ½ reactions together to create one large equation.
5) Simplify this equation by cancelling like expressions.
6) Check to make sure atoms and charge are balanced. DONE
