Iron Reacting with Hydrochloric Acid

Fe + 2HCl → FeCl2 + H2

Обзор

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.

Пример из жизни

Steel (iron) structures corroding faster in coastal areas is partly due to the reaction of iron with acidic chloride-containing sea spray.

Промышленное значение

Iron(II) chloride is used as a reducing agent, in water treatment as a flocculant, and in the production of iron-based pigments.
