Copper(II) thiocyanate can be prepared from the reaction of concentrated solutions of copper(II) and a soluble thiocyanate salt in water, precipitating as a black powder. [2] [3] With rapid drying, pure Cu(SCN) 2 can be isolated. Reaction at lower concentrations and for longer periods of time generates instead copper(I) thiocyanate. [4]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

To a copper(II) solution sulphurous acid is added and then a soluble thiocyanate is added (preferably slowly, while stirring [7]). Copper(I) thiocyanate is precipitated as a white powder. [ 8 ] Alternatively, a thiosulfate solution may be used as a reducing agent.
Thiocyanate [6] is known to be an important part in the biosynthesis of hypothiocyanite by a lactoperoxidase. [7] [8] [9] Thus the complete absence of thiocyanate or reduced thiocyanate [10] in the human body, (e.g., cystic fibrosis) is damaging to the human host defense system.

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).
