.
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 BaSO

.
Source and Purity of Materials:
Barium formate was prepared by the reaction of the carbonate with formic acid.
Estimated Errors:
Temperature: The temperature was controlled to within ±0.02 °C.See note under Experimental Values.
