Walther Hermann Nernst German physical chemist (June 25, 1864 – November 18, 1941) Calculating the electrical potential at which there is no longer a net flux (movement) of a specific ion across a membrane.
chemical potential Wchem = ⇒ NRT X ln X N = number of moles associated with the concentration gradient R = gas constant T = absolute temperature X 1 / X 2 = concentration gradient electrical potential ⇒ Welectr = NzFE N = number of moles of the charged particles z = valency (number of + or – charges (e.g. K + : monovalent)) F = Faraday’s number E= strength of the electric field (V) 1 2
