Document Summary

Determine oxidation numbers in reactants and products of redox reactions, and identify oxidizing and reducing agents. Balance redox reactions, including those occurring in acidic or basic solution. Use the nernst equation to determine cell energy under non-standard conditions. Nitrogen can range in oxidation number from -3 to 5. Negative number indicates an abundance of electrons and that they can be lost more readily than a species with a more positive oxidation number. Leo says ger (lost electrons oxidation, gained electrons reduction) Species getting oxidized and reduced are always on the reactant side. 1. the sum of all oxidation numbers in a molecule or ion must equal the overall charge of the molecule or ion. 4. an alkali metal (group 1) is +1 and an alkaline earth metal (group 2) is +2. 5. hydrogen is typically +1, unless forming a compound with a metal, or boron, in which cases it behaves as a hydride with an oxidation of 1.
