Sažetak

This review deals with electrostatic potentials within solid/electrolyte interfaces. The electrostatic
potentials of several planes are defined and discussed: the inner surface potential affecting the state of
charged surface species due to interactions with potential determining ions (Ψ0), the potential affecting the
state of associated counterions (Ψβ), the potential at the onset of diffuse layer (Ψd) and the electrokinetic
potential (ζ). The relevance of zero values of these potentials is also discussed and the corresponding
points of zero charge are defined. Experimental methods for the measurement of the interfacial potentials
are presented. The relations between potentials and surface charges are given on the basis of the Surface
Complexation model. Some experimental findings are provided.
