Description
Organic compound, double salt of bivalent alkaline earth metal calcium, transitional metal copper and organic acetic acid. From water solutions crystallizes as hexahydrate.
Precursors
Mixing hot solutions of copper and calcium acetate
Chemical equation:
100.00
g of copper-calcium acetate hexahydrate
а 44.58
g of copper acetate monohydrate
and 157.34
g of calcium acetate monohydrate
is required.Dissolve compounds in hot water apart and then mix solutions into one container with intense stirring. Cooling or evaporation of a solution will cause double salt crystallyzation. After reaction will stop, filter the solution and use it for crystal growing.
You could observe that compounds ratio is not equimolar. The cause is that firstly crystallizes copper acetate which is slight soluble, then begins long period of evaporation of water excess, and only then begins crystallization of double acetate.
If there are 4 or more parts of calcium for 1 part of copper, double salt crystallizes immediately at solution cooling.
Reaction between copper(II) nitrate and calcium acetate
Chemical equation:
100.00
g of copper-calcium acetate hexahydrate
а 66.01
g of copper(II) nitrate hexahydrate
and 314.69

is required.Add to the flask with hot calcium compounds solution a copper compounds solution with heating and stirring. Cooling this mixture will cause forming a large amount of crystalline precipitate. Filter precipitate and wash it wish small amount of cold water, then filter the solution and use it for crystal growing.
