What is the color of copper carbonate?
The copper powder reacts with oxygen, forming an opaque coating of copper oxide that tends to be green or bluish-grey in color. This layer is termed the patina. Hence, the colour of copper carbonate is green.
Why do copper solutions turn blue?
In compounds copper sulphate, the blue colour is due to the light energy being used to promote or excite electrons that are in the atom of the copper when it’s combined with other things such as the sulphate or carbonate ions and so on. This again is energy being used to excite the electrons in the atoms or ions.
