Electrochemistry (Chemistry)

Recall cards on electrochemistry: a review of redox chemistry (oxidation numbers and their rules, oxidants and reductants, and the half-reaction method for balancing redox equations); galvanic cells (half-cells, anode and cathode, salt bridges, active and inert electrodes, and cell notation); electrode and cell potentials (the volt, standard cell potential, the standard hydrogen electrode, tabulated standard reduction potentials, and predicting spontaneity); the links among potential, free energy, and equilibrium (delta-G = -nFE, Faraday's constant, the relationship of E-degree-cell to K, and the Nernst equation); batteries and fuel cells (primary and secondary cells, the dry, alkaline, NiCd, lithium-ion, and lead-acid batteries, and the hydrogen fuel cell); corrosion (the electrochemistry of rusting and methods of protection such as galvanization, passivation, and sacrificial anodes); and electrolysis (electrolytic cells, overpotential, the Downs and chlor-alkali processes, and the stoichiometry relating charge to amount of substance produced).
