Conditions:
Room Temp: 298 $\pu{K}$
Compiler:
Methodology:
Constant temperature bath, thermometer, and an ultraviolet spectrophotometer.
Excess solute and solvent placed in closed glass bottles, mixed at room temperature for 24 hours on magnetic stirrers and temperature equilibrated for an additional 24 hours in a constant temperature water bath. After equilibrium was obtained aliquots of saturated solution were removed and diluted quantitatively for spectrophotometric analysis at 254 nm.
Sample Information:
- Scintillation grade, 99%, source not given.
- 200 Proof, source not given.
Measurement Errors:
Ambient temperature: T/K: precision ±0.05 x1: ±5% (relative error; compiler).
System Components:
- Naphthalene, $\ce{ C10H8 }$; [91-20-3] NIST WebBook
- Ethanol, $\ce{ C2H6O }$; [64-17-5] NIST WebBook
