Conditions:
Room Temp: Temperature $\pu{K}$
Compiler:
Methodology:
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 Saturated solution was withdrawn through a coarse filter and analyzed by specific gravity.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.
Sample Information:
- Purity not given, Kahlbaum, was recrystallized from alcohol to a melting point temperature of 80.1°C.
- Marked absolute, from Eimer and Amend and Chas. Cooper and Co., dried over calcium oxide and distilled before use.
Measurement Errors:
Ambient temperature: T/K: precision ±0.1. x1: ±8% (relative error, compiler).
System Components:
- Naphthalene, $\ce{ C10H8 }$; [91-20-3] NIST WebBook
- Ethanol, $\ce{ C2H6O }$; [64-17-5] NIST WebBook
