Which statement below is not true for a liquid-membrane based ion-selective electrode? ● A. Two reference electrodes measure the voltage difference across the ion-selective electrode organic polymer membrane. B. The organic polymer membrane separates the inner solution from the outer analyte solution. C. The organic polymer membrane is hydrophobic and is impregnated with a viscous organic solution containing an ion exchanger and sometimes a ligand specific for the analyte ion. O D. The potential difference across the organic polymer membrane occurs when the analyte ions embedded in the membrane diffuse into the inner aqueous solution creating a junction potential. O E. The potential difference is dependent only on the activity of anallyte ion in the outer solution.
