Surface tension of anionic surfactant solutions, sodium dodecyl sulfate (SDS) or sodium dodecylbenzenesulfonate (SBS) decreases remarkably in the presence of [Co(NH3)(6)]X-3 (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.
