(2) Water, H₂O; [7732-18-5] NIST WebBook

Original Measurements

Booth, H. S.; Everson, H. E.; Ind. Eng. Chem. 1948, 40, 1491-3.

Variables:

Ambient temperature: 25.0 °C (298.2 K)

Prepared by:

G.T. Hefter

Method/Apparatus/Procedure:

A known volume of water, typically 50 mL, was placed in a stoppered Babcock tube having a neck graduated 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 etermined by subtracting the undissolved solute measured directly in the neck of the tube from the total added.

Source and Purity of Materials:

1. "Highest grade commercial sample available"; no other details given.
2. Distilled.

Estimated Errors:

Ambient temperature: not specified.
