Industrial grade 98% copper sulfate
Copper sulfate (chemical formula: CuSO4), which is a white or off-white powder. Its aqueous solution is weakly acidic and blue.
China's main producing areas are Yunnan, Shanxi, Jiangxi, Guangdong, Shaanxi, Gansu, Hubei and other places also have minerals.
In the actual production and life, copper sulfate is often used to refine copper, and mixed with slaked lime to make pesticide Bordeaux mixture.
Copper sulfate is an important raw material for the preparation of other copper-containing compounds. Blended with lime milk to obtain Bordeaux mixture for use as a fungicide.
At the same time, copper sulfate is also an electrolyte when electrolytically refining copper.
The common form of copper sulfate is a crystal, and copper tetrahydrate sulfate ([Cu(H2O)4]SO4·H2O, copper sulfate pentahydrate) is a blue solid (crystal).
The aqueous solution exhibits a blue color due to the hydrated copper ions, so anhydrous copper sulfate is often used to test the presence of water in the laboratory.
Copper sulphate is a heavy metal salt, toxic, and the adult lethal dose is 0.9g/kg. If you eat too much, you should immediately eat a lot of protein-rich foods such as milk and egg white, or use EDTA calcium sodium to dissolve.
The oxidative zone of cholesteric copper deposits is also often found on the inner walls and pillars of mine shafts, which are crystallized from water in the mine.
The crystals of biliary crystals are plate-like or short-column, and these crystals are aggregated in the form of granules, blocks, fibers, stalactites, and hulls.
