Properties of Copper: Chemical, Mechanical and Physical

The aqueous solutions of copper ions in the oxidation state +II have a blue colour, whereas copper ions in the oxidation state +I are colourless. Copper and copper compounds give a greenish color to a flame. Mechanical properties of copper. The primary mechanical properties of copper—hardness, strength and ductility—determine its condition.
