Compilation - Barium formate with Water (IUPAC SDS Volume 73)
SDS Volume (4749)
Volume 73. Metal and Ammonium Formate Systems, p None
Original Measurements
Stanley, H.; Chem. News 89, 193 (1904).
Variables:
Room Temp: 0 - 100 °C
Prepared by:
St. Trendafilova, Chr. Balarew
Method/Apparatus/Procedure:
The isothermal method was used. The thermometer was graduated in tenths of a degree C. The barium content was determined gravimetrically as $\ce{baSO4}$.
Source and Purity of Materials:
- Barium formate was prepared by the reaction of the carbonate with formic acid.
Estimated Errors:
Ambient temperature: The temperature was controlled to within ±0.02°C.See note under Experimental Values.
Components:
- Barium formate, $\ce{ Ba(CHO2)2 }$; [541-43-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
Note: There are many arithmetical errors in this paper. The compilers have calculated and recalculated all the data in the above table.

(a) These values and the molality values were calculated by the compilers.
(b) The solid phase is: A = Ba(CHO2)2.
