The coacervation of a dialkyl dimethyl ammonium salt was induced by various electrolytes. The electrolyte concentration in which coacervation was observed was in the range of 0.01-0.2M, depending on the electrolyte type. The effectiveness order for coacervation was found to be: NaSCN > NaI > NaBr > NaCl > NaF. A correlation between the ionic radii of the anion and the concentration in which coacervation is induced, is suggested. This correlation indicates that the coacervation process depends on the degree of counter ion binding to the cationic surfactant.
