Abstract
Surface tensions of solutions of oxalic, malonic, succinic, glutaric a nd adipic acids in water and water + acetone (x(acetone) = 0.016, 0.03 3, 0.072, 0.117 and 0.171) mixtures at different temperatures for vary ing ranges of concentrations have been measured by means of the ring d etachment method. The data were analyzed using Gibbs equations and var ious thermodynamic functions have been evaluated. The results reveal t he nature of solute adsorption at the interface in these solvents.
