Method/Apparatus/Procedure:
A known volume of water, typically 50 mL, was placed in a stoppered Babcock tube having a neck grauated from 0 to 1.6 mL in steps of 0.02 mL. An excess of solute was added and the mixture allowed to come to equilibrium in a constant temperature bath then centrifuged. The amount of solute dissolved was determined by subtracting the undissolved solute, measured directly in the tube, from the total added.
Source and Purity of Materials:
- "Highest grade commercial sample available"; no other details given.
- Distilled.
Estimated Errors:
Ambient temperature: Not specified.
Components:
- Heptane, $\ce{ C7H16 }$; [142-82-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of n-heptane in water at 25.0°C was reported to be <0.04 mL (1)/100 mL (2). A similar request was reported for (1) in 40.0% (w/w?) aqueous sodium xylenesulfonate.
