Question

The selectivity of an ion-selective electrode is determined by the

Answer 1

An ion-selective electrode (ISE), also known as a specific ion electrode (SIE), is a transducer (or sensor) that converts the activity of a specific ion dissolved in a solution into an electrical potential. The voltage is theoretically dependent on the logarithm of the ionic activity, according to the Nernst equation.

Answer 2

The selectivity of the Ion selective electrode is determined by the conformation of the membrane.  

Ideally, the membrane lets the uptake of only one explicit ion into it. The analyte ion may be an anion or a cation.

Ion-selective electrode (ISE) is a systematic technique used to govern the activity of ions in an aqueous solution by determining the electrical potential.
