Method/Apparatus/Procedure:

Constant temperature bath and a precision thermometer. Mixtures of known concentrations put in open containers and placed in constant temperature to equilibrate. Samples were rocked while bath temperature slowly decreased. Solubility determined by visual noting the temperature at which the last trace of solid solute appeared.

Source and Purity of Materials:

(1) 99%, Ega, Steinheim, Germany, was used as received.
(2) 98%, Ega, Steinheim, Germany, was used as received.

Estimated Errors

Temperature: T/K: precision ±0.25.
Solubility: x1: ±0.001.
