In the agricultural field, Bordeaux liquid is generated after mixing with lime water. As a fungicide, it is used to control fungi on crops and prevent fruit from decaying. Because copper ions are toxic to fish, the amount must be strictly controlled. The aquaculture industry is also used as the main raw material of trace element copper as feed additive;

Dehydrating agent for alcohols and organic compounds. Gas desiccant.

For chemistry education, Basic Copper Sulphate is usually included in children's chemical experiment reagents for crystal formation experiments and copper electroplating experiments. Because of its toxicity, it is not recommended for young children. Basic Copper Sulphate can also be used to demonstrate the dehydration and weathering of crystals and the process of obtaining crystal water.

In the junior high school experimental examination, the substitution reaction between Basic Copper Sulphate and iron was used to verify the law of conservation of mass. It can also produce sulfuric acid.

Used in the medical field as an emetic.
