Ferric chloride is a covalent compound, with chemical formula FeCl3, which is easy to dissolve in water, and has strong water absorption. It is an important iron salt in daily production.

Ferric chloride is generally brown powder crystal, soluble in water and many organic solvents, such as methanol, ethanol, ether, etc. As an important chemical reagent, it is widely used in metal etching and wastewater treatment, such as hardware industry, electronic devices, watch industry, printing and dyeing wastewater treatment. Ferric chloride can also be used as raw materials for the production of ferrous chloride, calcium chloride, aluminum chloride, sulfuric acid and other chemical reagents. It can also be used in the production of complex iron salts, mordants for printing and dyeing production, thermal additives for glass production, etc.

Ferric chloride should ensure the safety of operation, can not appear leakage. Ferric chloride can damage human mucous membrane tissue, has strong corrosiveness to eyes, can burn skin, cause diarrhea, vomiting and collapse, etc., and has strong toxicity. It will produce corrosive toxic gas hydrogen chloride under high heat. Workers at work should wear gas masks and chemical protective clothing. In case of accidental contact, they should immediately wash with plenty of water and seek medical treatment.
