Cu and zn half
WebAug 9, 2024 · The process that occurs in this redox reaction is shown below as two separate half-reactions, which can then be combined into the full redox reaction. Oxidation: Zn ( s) → Zn 2 + ( a q) + 2 e − Reduction: Cu 2 + ( a q) + 2 e − → Cu ( s) Full Reaction: Zn ( s) + Cu 2 + ( a q) → Zn 2 + ( a q) + Cu ( s) Why does this reaction occur spontaneously?
