Method/Apparatus/Procedure:
Equal quantities of diphenylthiocarbazone were added to aqueous solutions with different amounts of tetrachloromethane in several flasks. The contents of the flasks were shaken for 5 minutes and left to stand for 1 hour. The mixtures were then filtered through a paper filter and then concentration measurements were made by spectrophotometry. The turning point on the graph of optical density versus tetrachloromethane concentration was taken as the measurement.
Source and Purity of Materials:
- Source and purity not given.
- Distilled (compiler).
Estimated Errors:
Ambient temperature: ±1 K (compiler).
Mass concentration (m/v) (1): See above.
Components:
- Tetrachloromethane, $\ce{ CCl4 }$; [56-23-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
