Magnesium Reacting with Steam

Mg + H2O → MgO + H2

Übersicht

Magnesium reacts with steam to produce magnesium oxide and hydrogen gas. The reaction is vigorous and highly exothermic. Hot magnesium burns with an intense white flame even in steam, making this a dramatic and instructive demonstration of the high reactivity of magnesium.

Alltägliches Beispiel

Magnesium fires cannot be extinguished with water because magnesium reacts with steam, producing hydrogen gas that adds fuel to the fire.

Industrielle Bedeutung

This reaction is a safety concern in magnesium processing plants and during fires involving magnesium components. Special dry chemical or sand extinguishers are required.
