Abstract

A previously published research ^2^ with membranes of a BeO‐containing 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 alkaline solutions, which may contain considerable amounts of Na^+^ by the side of K^+^, the glass electrodes are very suitable for the determination of the pK. The responsiveness of the electrodes to K^+^ and to the other monovalent cations can be expressed as a characteristic constant.
