Method/Apparatus/Procedure:
Constant temperature bath and a precision thermometer.
Mixtures of known concentrations sealed in glass ampoules and placed in constant temperature to equilibrate. Samples were rotated while bath temperature slowly increased. Solubility determined by visual noting the same temperature at which the last trace of solid solute disappeared.
Source and Purity of Materials:
(1) Purity not specified, P.O.Ch., Gliwice, Poland, was vacuum sublimed to a melting temperature of 80.25 ºC.
(2) Initial purity not specified, P.O.Ch., was dried over sodium metal and fractionally distilled to a final purity of 99.9+ % purity.
