Ferric chloride is a red-orange solid that has hygroscopic properties. Chemical Formula: FeCl 3. Layman's explanation: Ferric chloride is a corrosive chemical, thus, it is used to deodorize sewage and industrial waste by partially reducing to ferrous chloride.It is also employed as an engraving reagent on metal surfaces. Other applications include its use as a flocculating agent in water treatment.hemical Formula: FeCl 3.
