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, 5 mL samples of the saturated solution were taken by pipette, diluted to 25 mL with water and titrated against 0.1 N sodium hydroxide solutions by using phenolphthalein indicator.
Source and Purity of Materials:
- Source not specified; purity not specified; dried over anhydrous $\ce{K2CO3}$ and repeatedly distilled over $\ce{P2O5}$.
- Source not specified; purity not specified; purified by crystallization from water.
Estimated Errors:
Ambient temperature: Not reported.
Mass concentration (m/v) (1): Not reported.
