How is copper II sulfide formed?
Prepared by melting an excess of sulfur with copper(I) sulfide or by precipitation with hydrogen sulfide from a solution of anhydrous copper(II) chloride in anhydrous ethanol.
What are the properties of copper?
Copper is a reddish metal with a face-centered cubic crystalline structure. It reflects red and orange light and absorbs other frequencies in the visible spectrum, due to its band structure, so it as a nice reddish color. It is malleable, ductile, and an extremely good conductor of both heat and electricity.
What is copper II sulfate made of?
Cupric sulfate is a salt formed by treating cupric oxide with sulfuric acid. It forms as large, bright blue crystals containing five molecules of water (CuSO4∙5H2O) and is known in commerce as blue vitriol. The anhydrous salt is produced by heating the hydrate to 150…
