An ion-selective electrodes a sensor that converts the activity of a specific ion dissolved in a solution into an electrical potential. The voltage is theoretically then dependent on the logarithm of the ionic activity, according to the Nernst equation, which is:
E(cell) = Eº(cell) - (RT/nF * ln(Q))
