ABSTRACT:
A silver/silver halide electrode is prepared by coating portions of a layer of silver with a metal selected from the group consisting of chromium and nickel or mixtures or alloys of nickel and chromium and overall treating with an oxidizing agent in the presence of halide ions to form a silver halide layer on those portions of the silver layer not covered by metal. The electrodes can be used as assaying electrodes such as for halide ions or as reference electrodes. Reference elements formed from the reference electrodes are useful in providing ion-selective membrane electrodes.
