Ferric chloride is an orange to brown-black solid. It is slightly soluble in water. It is noncombustible. When wet it is corrosive to aluminum and most metals. Pick up and remove spilled solid before adding water. It is used to treat sewage, industrial waste, to purify water, as an etching agent for engraving circuit boards, and in the manufacture of other chemicals. Ferric chloride, solution appears as a colorless to light brown aqueous solution that has a faint hydrochloric acid odor. Highly corrosive to most metals and probably corrosive to tissue. Noncombustible. Used in sewage treatment and water purification.

It serves as a catalyst in organic synthesis.It acts as an indicator in the analysis of copper, selenium and arsenic, and in the determination of phenol, cholesterol and choline.It is used in wastewater treatment, printed circuit board etching, stainless steel etching and as a mordant.It is a good substitute for solid ferric chloride.Among them, high-purity grade HPFCS is used for high-demand cleaning and etching in the electronics industry.

Liquid ferric chloride is a highly efficient and low-cost flocculant for municipal and industrial wastewater treatment.It has significant effects in precipitating heavy metals and sulfides, decolorization, deodorization, degreasing, sterilization, phosphorus removal, and reducing effluent COD and BOD.
