Zinc and Copper Sulfate Displacement

Zn + CuSO₄ → ZnSO₄ + Cu

Aperçu

Zinc is oxidized from Zn⁰ to Zn²⁺ while copper is reduced from Cu²⁺ to Cu⁰ in this classic redox displacement reaction. Zinc loses two electrons (oxidation) that are gained by copper ions (reduction). The blue CuSO₄ solution becomes colorless as copper metal deposits on the zinc.
