Iron is a metallic element having the chemical formula Fe. Due to its reactivity with other elements, pure metal iron is scarcely found in nature, although it is one of the most abundant elements on the Earth's crust. Iron (II) sulfate, which is one of the most common iron compounds, is primarily used in manufacturing inks and dyes. It can also be medically administered as a remedy for iron-deficiency anemia.
