Lane's process for manufacturing hydrogen involves alternating "gassing" (oxidation) and "vivificati — Hydrogen Chemistry Question

💡 Solution & Explanation

Lane's process involves passing superheated steam over red-hot iron, forming magnetic iron oxide ($Fe_3O_4$) and $H_2$. To regenerate the iron (vivification), the $Fe_3O_4$ is reduced back to metallic iron using water gas ($CO + H_2$).
