Large quantities of hydrogen are required these days in industry for various purposes. Water is found to be the industry raw material from which hydrogen can be obtained . One of the important methods for the commerical production of hyrogen in Lane's process in which steam is passes over hot iron. Iron decomposes steam with formation of magnetic oxide `(Fe_(3)O_(4))` and hydrogen.
