Answer 2

CuO can be converted to CuSO4 by reacting it with sulfuric acid (H2SO4).

CuSO4 can be converted to Cu(OH)2 by adding a base, such as sodium hydroxide (NaOH), to precipitate the copper hydroxide.

Cu(OH)2 can be converted back to CuSO4 by reacting it with sulfuric acid (H2SO4).

CuSO4 can be further reduced to Cu by using a reducing agent, such as metallic zinc (Zn), which displaces the copper from the sulfate compound.
