Popis:	The dissociation equilibrium between uncharged local anesthetic lidocaine (LC) and charged local anesthetic LC (LC•H+) in a surface-adsorbed film was investigated by measuring the surface tension and pH of aqueous solutions of a mixture of hydrochloric acid and LC. The surface tension values decreased slightly with increasing total molality mt at 0≤X2≤0.5, where X2 is the mole fraction of LC in the mixture, while they decreased rapidly with increasing mt at 0.5
