 Solubility System: Copper formate with Water

---

Components:
   (1) Copper formate; Cu(CHO2)2; [544-19-4]  NIST Chemistry WebBook for detail
   (2) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail

Original Measurements:
   Calame, P., Z. Physik. Chem. 27, 401 (1898).

Variables:
   Temperature = -0.76 ºC to -0.23 ºC

Prepared By:
   Chr.Balarew

Experimental Data:   (Notes on the Nomenclature)
(Please see footnotes following the table(s).)   

Freezing points of the Cu(CHO₂)₂-H₂O system.

t/°C	Phase	Mass Fraction w1	m1 [mol kg-1]a	Solid Phase(s)
-0.760	Liquid	3.72	0.252	ice
-0.417	Liquid	1.90	0.126	ice
-0.230	Liquid	0.96	0.063	ice

Notes:
   ^a  These values were calculated by the compiler.

Method/Apparatus/Procedure:
   Freezing point determinations were made with a Beckmann apparatus having a thermometer graduated in 0.01 °C. The copper content was determined gravimetrically.

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

Estimated Errors:

   Temperature: ±0.01 °C.
