Zinc and Copper Sulfate Displacement
Zn + CuSO4 → ZnSO4 + Cu
Übersicht
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.
