Identify the atoms that are oxidized and reduced, the change in oxidation state for each, and the oxidizing and reducing agents in each of the following equations: Note, for the change in oxidation state, give the total change for that element. E.g. Br2 → 2Br-; each bromine atom gains 1 electron (ox state = 0 → ox state = -1), for a total gain of 2 electrons (total change of -2)

Guidelines for Balancing Redox Equations: Determine the oxidation states of each species. Write each half reaction and for each: Balance atoms that change oxidation state. Determine number of electrons gained or lost Balance charges by using H+ (in acidic solution) or OH- (in basic solution). Balance the rest of the atoms (H's and O's) using H2O. Balance the number of electrons transferred for each half reaction using the appropriate factor so that the electrons cancel. Add the two half-reactions together and simplify if necessary.
