Web20 dec. 2005 · V Eq. is the equilibrium potential (Nernst potential) for a given ion. It is common to use the ion symbol as a subscript to denote the equilibrium potential for that ion (e.g., V K, V Na, V Cl, V Ca, etc.).If only one ionic species is present in the system, and/or channels for only one ionic species are present (and open), then V Eq. will also be the … WebThe ionic strength of a solution is a function of the concentration of all ions present in a solution: (5) I = 1 2 ∑ i z i 2 c i. Here, c i and z i are the molar concentration and the charge of ion i. The sum is taken over all ions in the solution. Due to the square of z i, multivalent ions contribute particularly strongly to the ionic strength.
