Original Measurements

Speyers, C. L.; Am. J. Sci. 1902, 14, 293-302.

Variables:

Room Temp: Temperature $\pu{K}$

Prepared by:

W.E. Acree, Jr.

Method/Apparatus/Procedure:

Experimental procedure only marginally described by author. Excess solute and solvent were equilibrated in a constant temperature water bath for between 10-30 minutes. Saturated solution was withdrawn through a coarse filter and analyzed by specific gravity. Author noted that evaporation to dryness and weighing the residue was subject to too much decomposition.

Source and Purity of Materials:

1. Purity not given, Kahlbaum, was recrystallized from alcohol to a melting point temperature of 80.1°C.
2. Purity unknown, several sources listed, washed with water, sulfuric acid, dried over calcium chloride and distilled.

Estimated Errors:

Ambient temperature: T/K: precision ±0.1. x₁: ±8% (relative error, compiler).
