Ferric chloride (\(FeCl_{3}\)) is an inorganic salt that is widely used as a coagulant in water and wastewater treatment, a mordant in textile dyeing, and an etching agent in electronics manufacturing. It is a corrosive, poisonous substance that appears as dark brown or yellow-brown crystalline solid or an orange-brown aqueous solution with a faint hydrochloric acid odor. Its primary commercial use is in water purification processes, where it helps remove impurities and clarify water.
Common uses
- Water treatment: Coagulates and precipitates impurities in drinking water and wastewater, helping to remove solids and clarify the water.
- Electronics: Used as an etching agent in the production of printed circuit boards.
- Art and photography: Used to etch designs onto metal plates for printmaking and in the cyanotype process to create blueprints.
- Textile dyeing: Acts as a mordant to fix dyes onto fabrics, which enhances color fastness.
- Medicine: Historically used as an astringent or styptic (to stop bleeding).
