According to the Nernst equation, the equilibrium potential for any ion, Ejon, distributed across a membrane is dependent on the internal, [lon]in, and external, [lon]out, concentrations of the ion (in moles or grams/liter); the valence of the ion, z (an integer); the absolute temperature, K; Faraday's constant, F; and the universal gas constant, R. Eion = ( R ) 2.303 log10 (Ionlout Tomlin If Faraday's constant is approximately 96,500 coulombs/mole, and the equilibrium potential for sodium ions across a skeletal...
