Document Summary

Something is going to lose or gain electrons: oxidation states. What-if scenarios pretending as if everything is in an ionic bond. Low oxidation states(negative) have a lot of electrons. High oxidation states(positive) have few electrons: half-reactions. Times the whole half reaction by whole numbers so that you balance when you recombine them. Balancing with half-reactions: oxygen can help balance the reaction and water, in acidic solution. A) balance all atoms except o and h. C) balance hydrogen atoms by adding h+ Multiply one or both half rxns by integer so that. # e"s gained = # e"s lost. Check that the elements and charges are balanced: in basic solution. Balance the oxidation and reduction half reactions as if it occurs in an acidic solution (steps 1-5) To both sides of the reaction add the number of oh- ions that is equal to the number of h+ ions.
