Method/Apparatus/Procedure:
The trichloroethene and air mixtures were prepared in gas cylinders under pressure. An Oxford vaporizer was used to produce a high concentration of trichloroethene. Water was equilibrated with the gas mixture by a simple bubbling technique. The saturated aqueous solution was treated with pyridiene and $\ce{HCl}$ solution to generate a yellow color which was measured spectrophotometrically using a filter transmitting at 430 m. u.
Source and Purity of Materials:
- Source and purity not given.
- Distilled.
Estimated Errors:
Ambient temperature: ±0.5 K (compiler).
Mass concentration (m/v) (1): ±3.0%.
Components:
- Trichloroethylene, $\ce{ C2HCl3 }$; [79-01-6] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
