Abstract

The interface between the Aerosil OX 50 colloidal dispersion and the electrolyte solution was studied using three independent methods: titration for surface charge density determination, conductivity, and electrophoretic mobility. It is shown that all three methods give good agreement for the surface charge density in 10-2 rnol/dm-3 KCl solutions, but less so for 10-3 mol/dm-3.
