Iron reacts to form many colored compounds. It can also displace hydrogen gas from acids as it is a fairly reactive metal. It undergoes exothermic redox reactions. The most common reaction of Iron is its reaction with oxygen to form Iron Oxide which is rust. Another common reaction of Iron is its reaction with sulfur which is a strongly exothermic reaction that produces a charcoal grey substance. It forms the chemical formula of FeS. However, it can also react with sulphur to form FeS2(pyrite) which is a brassy, shiny mineral sometimes mistaken for gold. As Iron is a fairly active metal, it can easily displace hydrogen from mineral acid solutions. Iron is a cation, it also reacts with anions to form a precipitate. A precipitation reaction of Iron occurs upon mixing aqueous solutions of potassium hydroxide and iron chloride. When these two compounds are mixed the product is a salt, KCl and a precipitate of Iron hydroxide. When Iron is reacted with hydronium ion, it oxidizes by giving off two
