Ferric hydroxide is a chemical compound with the formula Fe(OH)₃. It appears as a reddish-brown solid and is commonly found in nature as a mineral. This compound is formed when iron ions react with hydroxide ions in a solution, often occurring in water treatment processes to remove impurities. In addition to its role in water purification, ferric hydroxide is used in various applications, including as a pigment in paints and coatings. It is also utilized in the production of iron and steel, contributing to the overall efficiency of these industries by helping to manage iron content.
