Abstract

Surface tension (γ, mN/m) of potassium halide salts with water and interfacial tension (IFT) (±0.01 mN/m) of benzene interfaces with water are reported at 298.15 K temperature. The 0.1, 0.5 and 1.0 mol kg-1potassium fluoride (KF), chloride (KCl), bromide (KBr) and potassium iodide (KI) solutions were studied. TheKCl, KBr, KFandKIincreased the surface tension by 5.2, 4.0, 3.1 and 3.0%, respectively, with salt–water interaction influence by anionic sizes. The surface tension of water from air–water to benzene–water interfaces is decreased by 51% due to the benzene–water mutual interaction with dipolar and π-conjugation. TheKI, KF, KClandKBrsalts decrease the IFT by 63, 61, 61 and 56%, respectively, because of larger differences in sizes of the anions and theK+with individual salt. TheKIdeveloped stronger interactions with an induced potential of a large sizedI-anion that held the water engaged and integrated the aqueous phase with higher interfacial tension. The dipolar and π-conjugation interaction model is proposed with biphasic systems.
