Conditions:
Room Temp: 0 - 100 °C
Compilers:
St. Trendafilova, Chr. Balarew
Methodology:
The isothermal method was used. The solid and liquid phases were separated from each other by filtration. Each of the phases was then analyzed but no description of the analytical methods is given.
Sample Information:
- The calcium salt was prepared by the action of Kahlbaum pure acid on precipitated $\ce{CaCO3}$. Water was removed from the reaction mixture by evaporation and the solid was then recrystallized from water.
Measurement Errors:
Mass concentration (m/v) (1): No information is given.
System Components:
- Calcium formate, $\ce{ Ca(CHO2)2 }$; [544-17-2] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
