Iron III chloride Formula

Iron III chloride, which is otherwise known as ferric chloride is a compound made of iron and chloride with the formula FeCl3. It rarely occurs in its natural form which is the mineral molysite. Although, it can be industrially manufactured by combining iron and chlorine as follows:

\(\begin{array}{l}2Fe+3Cl_2\rightarrow 2FeCl_3\end{array} \)
