The solubility of potassium bromide in binary solvents formed by acetone and water was determined in the temperature range between (288.15 and 313.15) K at atmospheric pressure using an isothermal method. The reliability of the measured method used in this study was checked by comparing the experimental data with published data in the literature for the KBr-water system, and the method proved to be accurate. Experimental solubility data were correlated with Sechenov's equation.
