Ferric Chloride

Ferric Chloride is a chemical compound which is used the world over. It has a chemical formula of FeCl3 and is also commonly known as Iron (III) Chloride.

Ferric Chloride presents as crystals whose colour depends on the angled from which they are viewed, sometimes appearing dark green and sometimes appearing purplish-red. When dissolved in water, Ferric Chloride reacts exothermically, meaning that it generates heat, resulting in an orangey-brown Corrosive liquid which is used in a wide variety of applications from treating drinking water to sewage treatment and in the production of printed circuit boards.

Ferric Chloride also has a number of uses in the laboratory, most often as a Lewis Acid for catalysing reactions. In its anhydrous form, it is used as a drying reagent in some reactions.

Veterinarians use Ferric Chloride to treat animal claws which have been trimmed and where over-cropping has resulted in bleeding from the cut claw.

In industry, Ferric Chloride is used to test for corrosive properties of alloys and stainless steel, in particular where pitting of the metal has taken place.

Ferric Chloride should only be handled by persons with a thorough understanding of the potential hazards of this substance, which can cause serious burns to skin and eyes. Appropriate Personal Protective Equipment should be worn when working with this material, including safety coveralls, approved safety eye protection, safety gloves and safety footwear. MSDS (Material Safety Data Sheet) information should be read before working with Ferric Chloride.

In case of ingestion, medical attention should be sought immediately as Ferric Chloride is very Hazardous. Contact with skin may cause irritation, redness and blistering, with the amount of damage being depending on the length of contact. In case of skin contact, wash the area thoroughly with water and seek medical attention if symptoms persist.

Eye contact with Ferric Chloride can result in irritation, redness, corneal damage and can lead to blindness. Eyes should be thoroughly irrigated with water and medical attention should be sought.

Inhalation of Ferric Chloride dust will produce irritation to gastro-intestinal tract and respiratory system, characterised by sneezing, coughing and a burning sensation. Severe over exposure to Ferric Chloride can result in lung damage and choking, which can lead to death.

Containers of Ferric Chloride should be stored in a cool, dry area and should be kept away from heat. Keep away from sources of ignition. Never add water to this product. Handle in a well-ventilated area or use fume extraction or personal respiratory equipment where ventilation is insufficient. Corrosive materials such as Ferric Chloride should be kept locked away in a safe area, out of the reach of children and animals.
