Terms- Oxidation- reduction reactions involve the transfer of electron- Oxidation- the loss of an electron(s)- Reduction- the gaining of an electron(s)- Can remember this with “OIL RIG”B. Balancing a redox equations: there are 5 steps to balancing- Step one: split the redox equation into half reactions, meaning to group like elements together- from the reactant side and the product side- Step two: find the balanced half reactions using the table from the textbook- page 523-525.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Step three: balance all O and H atoms. To balance oxygen, add H2O. To balance hydrogen, add H+.- Step four: multiply the half reactions so that they contain an equal number ofelectrons. (You want the electrons to cancel out.)- Step five: add the half reactions, making sure to cancel identical
