Copper sulfate, also known as blue alum, with chemical formula CuSO4, is white powder without water, blue powder with water, or light grayish green due to impure. It is a soluble copper salt. The common form of copper sulfate is its crystal. Copper sulfate tetrahydrate ([Cu (H2O) 4] SO4 · H2O, copper sulfate pentahydrate) is a blue solid. Its aqueous solution is blue due to hydrated copper ions, so anhydrous copper sulfate is often used to test the existence of water in the laboratory. In real production and life, copper sulfate is often used to refine refined copper, which can be mixed with hydrated lime to produce pesticide Bordeaux liquid. Copper sulfate is a heavy metal salt, toxic, and the lethal dose for adults is 0.9g/kg. If you eat by mistake, you should immediately eat or drink protein rich foods such as milk and egg white, or use EDTA calcium sodium salt to detoxify. White anhydrous copper sulfate powder is blue after dropping into water

It is mainly used as textile mordant, agricultural pesticide, water bactericide and preservative, as well as tanning, copper electroplating, mineral processing, etc. It is also used as astringent and disease prevention medicine. It is also an agricultural bactericide. Used as analytical reagent, mordant and preservative.

(1) It is used as chemical fertilizer in agriculture. (2) . is the raw material for making potash. (3) The dyestuff industry is used to make intermediates. (4) The glass industry is used as a clarifier. (5) The perfume industry is used as an auxiliary. (6) Used medicinally as a laxative. (7) The food industry is used as a general additive.

Ferrous sulfate: alias: ferrous sulfate, ferrous sulfate heptahydrate, green alum, drying ferrous sulfate. It can be used as reducing agent in electroplating plant, flocculant in industrial wastewater, precipitant in printing and dyeing plant, raw material in Tiehong plant, raw material in pesticide plant, raw material in chemical fertilizer plant, fertilization in ferrous sulfate flowers, etc. It is widely used for flocculation, clarification and decolorization of printing and dyeing, papermaking, domestic sewage and industrial wastewater. Ferrous sulfate can also be used to treat chromium containing wastewater and cadmium containing wastewater Equal high alkalinity and high chroma wastewater treatment can reduce a large amount of investment in neutralization acid.

Methyl chloroformate is the methyl ester of chloroformic acid and is an oily liquid with a color that is anywhere from yellow to colorless. It is also known for its pungent odor. Methyl chloroformate is used in the organic synthesis of medicine and pesticide, and also in the preparation of tear gas. In the pesticide industry, it is mainly used to prepare herbicide miecaoling and fungicide carbendazim.
