This video is a basic visual demonstration of the difference in colour between iron(II) and copper(II) salts.
It is easy to mistake copper(II) carbonate for an iron(II) salt because most iron(II) salts are usually green in colour.
However, copper(II) carbonate is characteristically dry and powdery, while iron(II) salts are usually crystalline and shiny.
Copper(II) carbonate does not have the typical blue colour of most copper(II) salts. However, not all copper(II) salts are blue as taught in high school Chemistry.
