Method/Apparatus/Procedure:
About 100-500 mL (2) was placed in a glass cylinder and 10-50 mg of an insoluble indicator was added and (1) was microburetted until the indicator floated to form a colored thin layer on the cylinder wall 2-3 cm above the liquid layer. After each drop of (1), the mixture was vigorously mixed fr 0.5-1.5 min.

Heptane with Water
Components:
(1) Heptane,
$\ce{ C7H16 }$;
[142-82-5]
NIST WebBook
(2) Water,
$\ce{ H2O }$;
[7732-18-5]
NIST WebBook
Experimental Values:
The solubility of heptane in water at 20°C was reported to be 0.06 g(1)dm-3(2).
The corresponding mass percent and mole fraction, x1, calculated by the compiler are 0.006 g(1)/100 g sln and 1.1 × 10-5. The assumption that 1 dm3 sln = 1 kg sln was used in the calculation.
