Conditions:
Room Temp: 0 - 100 °C
Compilers:
St. Trendafilova, Chr. Balarew
Methodology:
The isothermal method was used. The thermometer was graduated in tenths of a degree C. The analytical method is not described.
Sample Information:
- Calcium formate was prepared by the reaction of the carbonate with formic acid.
Measurement Errors:
Ambient temperature: The temperature was controlled to within ±0.02°C.See note under Experimental Values.
System Components:
- Calcium formate, $\ce{ Ca(CHO2)2 }$; [544-17-2] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
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.
| $T$ (°C) | 100w1 | g1/100 g H2O | m1 (mol/kg) b | Phase (s) () a |
|---|---|---|---|---|
| 0.0 | 13.79 | 16.00 | 1.23 | A |
| 51.7 | 14.76 | 17.32 | 1.33 | A |
| 100.0 | 15.46 | 18.29 | 1.41 | A |
(a) The solid phase is: A = Ca(CHO2)2.
(b) The molality values were calculated by the compilers.
(c) None
