Copper Displaced by Iron

Fe + Cu²⁺ → Fe²⁺ + Cu

Tổng quan

Iron reduces copper(II) ions to metallic copper while being oxidized to iron(II). This reaction proceeds because iron has a more negative standard reduction potential (-0.44 V) than copper (+0.34 V), making it a stronger reducing agent. The net cell potential is +0.78 V.
