These values were calculated by the compilers.
Method/Apparatus/Procedure:
Freezing point determinations were made with a Beckmann apparatus having a thermometer graduated in 0.01 °C. The calcium content was determined gravimetrically.
Source and Purity of Materials:
Kahlbaum or Merck reagents were used.
Estimated Errors:
Temperature: ±0.01 °C.
