Studies on Zeta Potential of Particles of (i) Sodium Oleate, (ii) Oleic Acid and their Mixtures Dispersed in Water

In this paper, Zeta potential of two component systems H₂O+Na oleate, H₂O+Oleic acid as well as of a three component system, H₂ O+Na oleate+Oleic acid has been studied with an ultramicroscope fitted with a special type of electrophoretic cell. It has been found that in both the two component systems, the Zeta potential decreases gradually and then increases with the increase of sodium oleate solution or oleic acid solution but when the three components are mixed together, two peaks are found. An attempt has been made to explain the results.
