Original Measurements

Smagowski, H.; Zesz. Nauk. Wydz. Mat., Fiz. Chem., Univ. Gdanski, Chem. 3, 45-53 (1974).

Variables:

Ambient temperature: 298 K

Prepared by:

V.P. Sazonov

Method/Apparatus/Procedure:

The titration method was used: 25 mL of (1) and an amount of (2) exceeding the solubility were placed in 50 mL volumetric flasks. The flasks were closed by ground glass stoppers and stored at the required temperature in a thermostat for 45 hours, with intensive stirring every several hours. After this, 2 mL samples of the saturated solution were taken by pipette, diluted to 25 mL with water-less acetic acid and titrated by 0.05 N HClO₄ by using crystal violet indicator.

Source and Purity of Materials:

1. Source not specified; purity not specified; dried over anhydrous K₂CO₃ and repeatedly distilled over P₂O₅.
2. Obtained by mixing of methanol solutions of sodium hydroxide and the acid in stoichiometric amounts; purified by crystallization from a mixture of water and methanol; purity not less 99 mass%.

Estimated Errors:

Ambient temperature: Not reported.
Mass concentration (m/v) (1): Not reported.
