Variables:
Ambient temperature: One temperature
Prepared by:
Method/Apparatus/Procedure:
A small excess of solute in water was agitated for a period of 4-48 hours (the exact time for equilibration was not reported in single cases) and then filtered. The saturated solution was extracted with a small volume of methylene chloride which was then assayed spectrophotometrically. At lease two independent determinations were carried out.
Source and Purity of Materials:
- Commercial product (Aldrich or Eastman), used as received.
- Source and purity not specified.
Estimated Errors:
Ambient temperature: ±1 K (authors).
Mass concentration (m/v) (1): ±10% (authors).
Experimental Values:
| T (°C) | C1 (mol/dm3)b | x1a | Cm1 (g(1)/dm3)a |
|---|---|---|---|
| 25.0 | 2.0 x 10-5 | 3.61 x 10-7 | 4.32 x 10-3 |
