Copper sulfate at room temperature for the dark blue granular crystals or blue granular crystalline powder, toxic, odorless, with a metallic astringent taste, the copper sulfate solution concentration and crystallization, you can get blue crystals of copper sulfate pentahydrate, commonly known as bile alum, copper alum, or blue alum, the relative density of 2.284. bile alum is very stable at room temperature and normal pressure, do not deliquesce, in the dry air will be weathered gradually, heated to 45 ° C to lose two molecules of crystalline water, 110 ° C to lose four molecules of crystalline water, 150 ° C to lose all the water of crystallization and become anhydrous. When heated to 45ºC, it loses two molecules of crystallization water, 110ºC, it loses four molecules of crystallization water, 150ºC, it loses all crystallization water and becomes anhydrous. Anhydrous material is also easy to absorb water into bile alum. Often use this property to test whether some liquid organic matter contains trace water. The alum will be heated to 650 ºC high temperature, can be decomposed into black copper oxide, sulfur dioxide and oxygen. Copper ions in copper sulfate can destroy the three-dimensional structure of proteins, so that the denaturation. Determination of protein concentration is often added to the protein base, and then added to the copper sulfate solution, the solution will turn purple, this reaction is known as the double urea reaction. Copper sulfate is one of the more important copper salts, which is widely used in electroplating, printing and dyeing, pigments, pesticides and so on.
Copper sulfate in in agricultural production:
Copper sulfate is used as a trace element fertilizer, copper is a plant normal life activities necessary for the seven trace elements, involved in plant growth and development process of a variety of metabolic reactions. Can chlorophyll stability, prevent chlorophyll from premature destruction, promote crop absorption, crop green loss in the absence of copper, fruit trees lack of copper, fruit small, hardened flesh, serious fruit tree death, copper-sensitive crops are cereal crops such as wheat, barley, oats, etc., mainly used for seed treatment and extra-root fertilizer. Copper is a component of polyphenol oxidase, ascorbate oxidase, cytochrome oxidase, etc. It is involved in the redox process in plants. It also exists in the chloroplast plastocyanin, involved in photosynthesis electron transfer. Most of the physiological functions of copper in plants are related to enzyme activities. The important physiological functions of these copper-containing oxidizing enzymes are participation in respiration and photosynthesis, which are directly related to the formation of chlorophyll, and also have a significant impact on nitrogen metabolism in plants. Copper sulfate as a trace element copper has the advantages of being fully water-soluble, easily absorbed and low in price. In the production of copper sulfate, it is necessary to pay attention to the dosage, and excessive dosage will be harmful to the crop.
