Iron Reacting with Hydrochloric Acid

Fe + 2HCl → FeCl2 + H2

Descripción general

Iron dissolves in hydrochloric acid to produce iron(II) chloride and hydrogen gas. The reaction proceeds at a moderate rate, producing green iron(II) chloride solution and gas bubbles. Warming the acid or using powdered iron increases the reaction rate significantly.
