Method/Apparatus/Procedure:

The composition analysis was based upon a volumetric method described in [1]. In this method, further addition of solute to a volume of solution yielded, upon saturation, proportional amounts of undissolved solute residue which could be measured volumetrically. A plot of added solute mass versus volume of residue gave a straight line the intercept to which gave the solubility. Stoppered tubes with capillaries graduated in steps of 0.05 mL were used for the measurements. A know volume of solvent (50 ml) was added to the tube in a constant temperature bath and weighed quantities of the solid solute were added to the liquid. The mixture was then shaken for 5 minutes, returned to the bath for a minimum of 10 minutes, and centrifuged for 5 minutes. Then, the volume of residue was read. The procedures were repeated to ensure that the equilibrium had been reached.
