The gel layer develops on an electrode glass on its first contact with water. This hydration process has been shown to involve both an ion exchange of the alkali metal ions in the bulk glass with hydrogen ions from the aqueous solution and a rupture of the silicon-oxygen bonds by reaction with water

Some pH-responsive glass electrodes have been characterised with respect to gel layer thickness, durability and ion exchange capacity. Glasses with a low durability exhibited a thick gel layer and a high ion exchange capacity in comparison with high durability glasses. The electrochemical properties
## Abstract A previously published research ^2^ with membranes of a BeOβcontaining glass was continued. Electrodes of the glass in question show increasing responsiveness to monovalent cations according to the series: C~3~H~7~(NH~3~)^+^ < Li^+^ < Na^+^ < NH~4~^+^ < K^+^ < Rb^+^ < Ag^+^ < H^+^. In
