Method/Apparatus/Procedure:
About 200-500 mL (2) was placed in a ground-joint glass cylinder and 20-50 mg of an insoluble indicator (dithizon, phenolphthalein, etc.) was added, and (1) was microburetted until the indicator floated to form a colored thin layer on the cylinder wall above the liquid layer. Blanks were made to determine the excess of (1).
Source and Purity of Materials:
- Not specified.
- not specified.
Estimated Errors:
Mass concentration (m/v) (1): ±0.01 g(1) dm-3 sln (standard deviation from 6 determinations).
Components:
- Toluene, $\ce{ C7H8 }$; [108-88-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of toluene in water at 25°C was reported to be 0.65 g(1)dm-3 sln. The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.065 g(1)/100 g sln and 1.27 × 10-4.
The compiler's calculations assume a solution density of 1.00 g/mL.
