t/°CMole Fraction x1Mole Fraction x2
23.00.03960.9604
 Method/Apparatus/Procedure:
   Constant temperature bath, rotator, thermometer, and an uv/visible spectrophotometer.
Excess solute and solvent placed in screw-capped test tube and allowed to equilibrate for 3 days with gentle agitation in a constant temperature bath. Samples centrifuged for 30 minutes and concentrations were determined spectrophotometrically. Attainment of equilibrium verified by repetitive measurements 4 days later.
