- Cell EMF: E°cell = E°cathode − E°anode (cathode minus anode); E°cell > 0 → spontaneous (° < 0); Daniell cell: E°cell = 0.34 − (−0.76) = 1.10 V.
- Nernst equation: E = E° − (0.0592/n) log Q at 25°C; at equilibrium E = 0 → E° = (0.0592/n) log K; ° = −nFE°; F = 96500 C/mol.
- Faraday's law: w = MIt/(nF); t in seconds; n = 1 (), n = 2 (, ), n = 3 (); 2 A × 1 hr through deposits 2.37 g Cu.
- Conductance: Λm = Λ°m − A√C (strong); α = Λm/Λ°m (weak); Kohlrausch: Λ°m() = Λ°m() + Λ°m(HCl) − Λ°m(NaCl).
- Cell polarity trap: Anode = NEGATIVE in galvanic; Anode = POSITIVE in electrolytic. In BOTH: oxidation at anode, reduction at cathode ("AN OX RED CAT").
