Effect of Addition of Salts on Excess Enthalpy in Methanol–Carbon Tetrachloride Mixture

Resumo

The effect of dissolved sodium acetate (5 and 10%), potassium acetate (5 and 10%) and zinc acetate (5 and 10%) on the endothermic enthalpy of mixing in the binary system methanol–carbon tetrachloride has been investigated at 303.15 K in a displacement calorimeter with vapor space. Experimental values were fitted into a Redlich–Kister equation. Experimental values and predicted values were plotted against mole fraction of methanol and deviations were reported. The data obtained may be of interest to specialists in the field of thermodynamic of solutions.
