Method/Apparatus/Procedure:
250 mL bottles were filled with distilled, deionized water and sealed. Measured volumes of 1,1,2,2-tetrachloroethane were injected into the bottles through each bottle septum using a microliter syringe. The solute was in excess of the anticipated solubility limit. The bottles were shaken for one hour with a wrist-action shaker and allowed to equilibrate for about three weeks. Samples were then injected into a gas chromatograph equipped with a Carbo-pack column and a FID detector. The GC responses were compared with calibration plots to establish concentrations.
Source and Purity of Materials:
- Probably a commercial reagent, at least 99% pure, used as received.
- Distilled and deionized.
Estimated Errors:
Ambient temperature: ±0.5 K (compiler).
Mass concentration (m/v) (1): Not specified.
Components:
- 1,1,2,2-Tetrachloroethane, $\ce{ C2H2C14 }$; [79-34-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
