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.
