25. Which statements regarding ion-selective electrodes are FALSE?
(A) Ion-selective electrodes involve redox processes.
(B) A difference of 59.16n mV, where n is the charge on the analyte, builds up across the membrane for every factor-of-10 change in analyte activity in the outer solution.
(C) The ion-selective electrode responds to the activity of the ion in all forms in the solution, including both the frec analyte and that which is complexed by anions in solution.
(D) The smaller the selectivity coefficient for an interfering species, the less interference by that species.
(E) Ion-selective electrodes contain a membrane that selectively binds the ion of interest.
