 Notes:
   a  The molality 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 magnesium content was determined gravimetrically.

 Source and Purity of Materials:
   Kahlbaum or Merck reagents were used.

 Estimated Errors:

   Temperature: ±0.01 °C.
