Abstract (EN): This article describes a simple and inexpensive experimental technique, easy to set-up in a laboratory, for the measurement of solute solubilities in liquids (or gases). Experimental values of solubility were determined for the dissolution of benzoic acid in water, at 293-338 K, of 2-naphthol in water, at 293-373 K, and of salicylic acid in water, at 293-343 K. The experimental results obtained are in good agreement with the theoretical values of solubilities presented in literature. Empirical correlations are presented for the prediction of solubility over the entire range of temperatures studied, and they are shown to give the solubility value with very good accuracy.
