Magnesium Reacting with Hydrochloric Acid

Mg + 2HCl → MgCl2 + H2

Übersicht

Magnesium reacts vigorously with hydrochloric acid to produce magnesium chloride and hydrogen gas. The reaction is highly exothermic and proceeds rapidly with visible gas bubbles. Magnesium ribbon dissolves quickly with effervescence, and the solution becomes hot.
