WebSelectivity coefficients An electrode used to measure ion A selectively may also slightly responds to ion X. For instance, a pH electrode responds to Na + when [H +] 10-12 M and [ Na +] 10-2 M. The smaller the selectivity coefficient is, the less is the interference by X . The response of an I.S.E. is thus represented by = ± +∑ X z A A X X Webselective migration of ions across this membrane. No redox reaction occurs at the electrode surface. The most important example of an ion-selective electrode is the glass electrode used to measure pH. In this case, the electrode is sensitive to H+.
