Glass Ball as Bullet Solubility System: Calcium formate with Water
Components:
   (1) Calcium formate; Ca(CHO2)2; [544-17-2]  NIST Chemistry WebBook for detail
   (2) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
Original Measurements:
   Stanley, H., Chemical News 89, 193 (1904).

 Variables:

   Concentration = Composition at 0 ºC to 100 ºC.

 Prepared By:
   Chr.Balarew and St. Trendafilova

 Experimental Remarks:
   The molality values were calculated by the compilers.
Note: The compilers assume that as with the data for barium and strontium formates, there are errors in these data also. However, the compilers have not been able to recalculate the data because the primary weight data are not given in the paper.

 Notes:
   a  The solid phase is: A = Ca(CHO2)2.

 Method/Apparatus/Procedure:
   The isothermal method was used. The thermometer was graduated in tenths of a degree C. The analytical method is not described.

 Source and Purity of Materials:
   Calcium 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.
