Iron hydroxide, with the CAS number 11113-66-9, is an inorganic compound that typically appears as a brownish or reddish-brown solid. It is primarily composed of iron (Fe) and hydroxide (OH) ions, and it can exist in various forms, including goethite and lepidocrocite, depending on its crystallinity and hydration state. Iron hydroxide is insoluble in water, which makes it useful in various applications, including water treatment processes where it acts as a coagulant to remove impurities. It is also a key component in the formation of rust and is involved in the geochemical cycling of iron in natural environments. The compound exhibits amphoteric behavior, meaning it can react with both acids and bases. Additionally, iron hydroxide can undergo transformations to form other iron oxides, such as magnetite or hematite, under certain conditions. Its stability and reactivity are influenced by factors such as pH, temperature, and the presence of other ions in solution.
