Iron Reacting with Hydrochloric Acid

Fe + 2HCl → FeCl2 + H2

Ikhtisar

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.

Contoh Sehari-hari

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

Pentingnya dalam Industri

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