Web9 jun. 2015 · The basic structure of the ion-selective electrode calls for a membrane which excludes all ions except for the ion of interest. In this fashion, the potential generated across the membrane is generated only because that specific ion species is migrating across it. The ion species migrates across the membrane along a concentration … 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
