Surface pressures and surface potentials of spread monolayers of sodium octadecyl sulphate at the air/solution interface have been measured at 9·5°C for surface areas from 80 to 5000 Å2/ molecule on sodium chloride solutions (0·1, 0·01 and 0·001 M). The variations of surface potential and pressure with respect to surface area and electrolyte concentration in the sub-solution are analyzed in terms of current theories of the ionic double layer.
