1. Basic Copper Carbonateis used as an analytical reagent, for example, it can be used in biology to configure Fehling's reagent for identifying reducing sugars and Biuret reagent for identifying proteins, but it is usually used as-is;
  2. Used as a food-grade chelating agent and clarifying agent, used in the production process of preserved eggs and wine;
  3. Industrial field. Used in the manufacture of other copper salts such as cuprous chloride, copper chloride, copper pyrophosphate, cuprous oxide, copper acetate, copper carbonate, copper monoazo dyes such as reactive brilliant blue, reactive violet, etc.; in the coating industry for the production of ship bottoms Antifouling paint; used as the main salt and copper ion additive for all-bright acid copper plating in electroplating industry; used as mordant and oxygen promoter for fine dyeing cloth in printing and dyeing industry; used as catalyst for synthesis of perfume and dye intermediate in organic industry, methyl Polymerization inhibitor for methyl acrylate. Anhydrous salt is used to catalyze the conversion of acetal reaction. The anhydrous salt reacts with potassium permanganate to form an oxidant, which is used for the conversion of primary alcohols.

In the agricultural field, Bordeaux mixture is mixed with lime water, which is used as a fungicide to control fungi on crops and prevent fruits from rot; because copper ions are toxic to fish, the dosage must be strictly controlled. The aquaculture industry is also used as the main raw material of the trace element copper as a feed additive;

  1. Used as a dehydrating agent for alcohols and organic compounds. Gas desiccant.
  2. For chemical education, Copper Hydroxideis 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. Copper sulfate can also be used to demonstrate the process of crystal loss and weathering and obtaining crystal water. In the junior high school laboratory examination, the substitution reaction between copper sulfate and iron was used to verify the law of conservation of mass. Sulfuric acid can also be obtained.
  3. Used as an emetic in the medical field.
