Original Measurements
Calame, P.; Z. Phys. Chem. 27U, 401 (1898).
Variables:
Room Temp: -1.010 - -0.305 °C
Prepared by:
Method/Apparatus/Procedure:
Freezing point determinations were made with a Beckmann apparatus having a thermometer graduated in 0.01 °C. The zinc content was determined gravimetrically.
Source and Purity of Materials:
- Kahlbaum or Merck reagents were used.
Estimated Errors:
Ambient temperature: ±0.01°C.
Components:
- Zinc formate, $\ce{ Zn(CHO2)2 }$; [557-41-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
