Compilation - Barium formate with Water (IUPAC SDS Volume 73)
SDS Volume (4727)
Volume 73. Metal and Ammonium Formate Systems, p None
Original Measurements
Krasnicki, E. R.; Monatsh. Chem. 8, 595 (1887).
Variables:
Room Temp: 1 - 76 °C
Prepared by:
Method/Apparatus/Procedure:
The apparatus and method were described earlier [1]. The mixtures were shaken for 10-1.5 hours. Dilute sulfuric acid was added to a weighed sample. The mixture was evaporated on a water bath. The remaining sulfuric acid was driven off by heating to constant weight of barium sulfate.
Source and Purity of Materials:
- Barium carbonate was dissolved in formic acid to form the barium formate. The crystals were analyzed.
Estimated Errors:
Mass concentration (m/v) (1): The solubility is ±0.2 g/100 g water.

Experimental Data
Author's Comments: The solubility data (g/100 g H2O) are mean values obtained by the cooling and the heating method.
