This sequence represents the different oxidation states of copper, from +1 to +2 to +3.
HCL (hydrochloric acid) can react with copper (Cu) to form copper chloride (CuCl2).
Copper chloride can further react with water to form copper hydroxide (Cu(OH)2).
Copper hydroxide can be heated to form copper oxide (CuO).
Finally, copper oxide can be further heated to yield copper (Cu) in its highest oxidation state of +2.
