Method/Apparatus/Procedure:
   The titration method, as described in Dunnery and Atwood,² was used. Solutions and solvents were thermally equilibrated and held at constant temperature during titrations. Enough solution was taken to give a titer of 10 to 20 mL.

Source and Purity of Materials:
   (1) Source not specified; purified by methods as in Weissberger¹; ρ(30 °C) = 1125.0 g · L^-1,ρ(40 °C) = 1110.8 g • L^-1.
   (2) Source not specified; purified by methods as in Weissberger¹; ρ(30 °C) = 868.5 g·L^-1, ρ(40 °C) = 857.5 g•L^-1.
   (3) Source not specified; purified by methods as in Weissberger¹; ρ(30 °C) = 769.4 g·L^-1.ρ(40 °C) = 759.6 g•L^-1 .

Estimated Errors:

   Temperature: control to ± 0.1 K.
