Explain how an ion-selective electrode (ISE) operates by placing the steps in the correct order, beginning after the electrode is placed in the aqueous sample solution. The electrode is placed in an aqueous solution. Filling solution Answer Bank - Ag|AgCl reference electrode The concentration of the analyte ion in the external solution is determined from the potential difference. Ion-selective membrane The potential difference is measured using the internal and external reference electrodes. Analyte ions diffuse out of the membrane. Analyte ions in the external sample solution equilibrate with ion-exchange sites in the membrane. A charge imbalance, also called a potential difference, develops across the interface.
