 Experimental Data:   (Notes on the Nomenclature)
  
t/°CMole Fraction x1Mole Fraction x2
25.00.3300.670
 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 temperature at which the last trace of solid solute disappeared. Solubilities at 298 K interpolated from experimental values  using ln x1 versus 1/T graph.

 Source and Purity of Materials:
   (1) Purity, source and purification procedures not specified.
   (2) Reagent Grade, J.T. Baker Chemical Company, USA, was used as received.

 Estimated Errors:

   Temperature: T/K: ± 0.1. x1: precision ± 2 % (relative error; compiler).
