The author investigated the working mechanism of ion‐selective electrodes. The contradictions of theories deduced from so‐called analogous phenomena were discussed in detail. Based on experiments made by his research group he came to the conclusion that only the surface (the active groups located there) takes part in the potential‐determining reaction, and the bulk resistance of the membrane has a role only in the selection of the instrument used for potential measurement.
