Abstract
The surface tensions of aqueous solutions of four mixtures (hydrochloric acid–glycine hydrochloride, glycine hydrochloride–glycine, glycine–sodium glycinate, and sodium glycinate–sodium hydroxide) were measured as a function of total molality and mole fraction. The measurements correspond to the change in surface tension with variation of pH. The contribution of glycine hydrochloride to the increments in surface tension is equivalent to that observed for the aqueous solution of glycine, while the contribution of sodium glycinate is much larger than that of glycine. The variations in surface tension on mixing in the surface region are discussed using comparisons with mixtures of simple salts.
