Ferric Chloride Hexahydrate is a hydrated form of ferric chloride, which means it contains six water molecules per molecule of ferric chloride. It is a greenish-brown crystalline solid that is commonly used in water treatment, wastewater treatment, and metal surface treatment. This is used as a coagulant to remove impurities and contaminants from drinking water. Ferric Chloride Hexahydrate should be stored in a cool, dry, and well-ventilated area away from incompatible materials such as organic compounds, metals, and strong bases. It should also be kept away from sources of heat or ignition, as it can react vigorously with organic compounds and cause a fire or explosion.
