摘要：
Electrosurface characteristics of tungsten oxide in solutions of 1: 1 electrolytes are studied in a wide range of concentration and pH values. The dependence of the position of isoelectric point on the concentration of background electrolyte and the cation nature is revealed. The equilibrium constants of surface reactions, adsorption potentials of ions, specific surface conductivities, and degrees of dissociation of surface groups in the point of zero charge are calculated.
