Abstract

Surface tension of anionic surfactant solutions, sodium dodecyl sulfate (SDS) or sodium dodecylbenzenesulfonate (SBS) decreases remarkably in the presence of [Co(NH3)6]X3 (2.50 mM) (X− = Cl−, Br−, I−, or ClO4−) at 298 K, depending on the kind of counter anion X−. The magnitude of reduction is in the order ClO4− ≥ I− > Br− > Cl− for SDS solutions and ClO4− > Cl− > Br− > I− for SBS solutions at 0.03 mM surfactant concentrations.
