Iron Reacting with Hydrochloric Acid
Fe + 2HCl → FeCl2 + H2
Visão geral
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.

Exemplo do cotidiano
Steel (iron) structures corroding faster in coastal areas is partly due to the reaction of iron with acidic chloride-containing sea spray.
Importância industrial
O cloreto de ferro(II) é utilizado como agente redutor, no tratamento de água como floculante e na síntese química. A reação do ferro com ácidos é a base da decapagem do aço antes da galvanização ou do tratamento de superfície.
