Title: Ion selective electrode

Abstract: An ion-sensitive electrode for measuring the concentration of a predetermined ion in a liquid is described which employs a metal hydride, such as palladium hydride, or a metal-alloy hydride in proximity with, or in contact with, a mixture of an acid and the salt of the acid with the predetermined ion. The hydride may be precharged with hydrogen or may be charged in situ.
