Ferric chloride, the iron (III) chloride, has a wide range of applications. In industry, it is used for sewage treatment and drinking water purification, including arsenic removal; as a leaching agent in chloride hydrometallurgy; for etching copper through two-step redox reactions to produce copper (I) chloride and then copper chloride in printed circuit board manufacturing; and as a catalyst in the synthesis of ethylene dichloride from ethylene and chlorine. In the laboratory, it is commonly used as a Lewis acid to catalyze reactions such as the chlorination of aromatic compounds and Friedel–Crafts reactions of aromatics.

Product Usage
It is extensively used for turbidity removal in various industrial waters and for treating wastewater from industries such as mining, printing and dyeing, papermaking, food processing, and leather. It demonstrates excellent purification performance for slightly polluted water, algae-contaminated water, low-temperature, and low-turbidity raw water, and is particularly effective in treating high-turbidity raw water.
