Balancing Redox Reactions
1. Determine the oxidation state of all elements of interest
2. Identify which elements are changing state and which are oxidizing, and which are reducing
3. For half reactions:
a. Write skeletal reaction (oxidation half or reduction half)
b. Add e-s were needed (to balance charge)
c. Balance O H2O dont use O2 because youll introduce a different oxidation state; more complicated
d. Balance H using H+4.
4. Combine half reactions. May need to multiply through to cancel e-s
5. Cancel any redundant species
6. Final check charge and species balance
1. Redox: Please balance the following redox reactions.
??. ??2 + ????3 ??4 ? ????(????)3
