You are given some ferrous iodide and are asked to extract the iron through electrolysis. What can be said about the merits of molten versus aqueous FeI2?
Iron (II) iodide has a relatively low melting point. Electrolysis of the molten salt will probably produce solid metallic iron and liquid I2 as well as iodine vapor. The temperature need not be high enough to cause Fe to melt.
so Electrolysis of either the molten or aqueous salt will produce solid iron.
