Copper carbonate (CuCO3) mixed with sulphuric acid (H2SO4) produces copper sulphate (CuSO4).
Copper sulphate is a form of salt that can be manufactured by the chemical reaction described in your question, or it can be found in nature as a mineral in the form of chalcanthite, bonattite or boothite. It can be grown easily in crystal form and is often used as such in schoolroom chemistry lessons.
Uses for Copper Sulphate
The chief use for copper sulphate is in agriculture, where it is used as part of fungicides and insecticides. Farmers also use copper sulphate in sheep dip, and to dress sides and sterilize soil. Elsewhere, copper sulphate can be used to eradicate algae blooms, and can help control diseases such as malaria and bilharzia.
Perhaps the most everyday use for copper sulphate is in bookbinding glue, where it helps prevent the binding from becoming infested with insects.
