Ferric chloride or iron (III) chloride is a chemical compound with the formula FeCl₃. It is reddish-brown in color and highly acidic, and is commonly used to dissolve metals. Such as, copper and zinc, ferric chloride is an important chemical in water quality improvement processes, municipal wastewater treatment, and industrial wastewater treatment as a very good coagulant. It can remove phosphates and heavy metals such as lead, cadmium, mercury, etc. that are present in wastewater, wastewater treatment from industrial plants and communities, etc.
Inhalation Move the victim to fresh air and keep them in a position comfortable for breathing. If symptoms worsen, Get medical attention.
