Give reasons :Iron displaces copper from a solution of a copper salt. The reaction is deemed as a redox reaction. |
Answer» Fe (s) + CuSO4 (aq) → FeSO4 (aq) + Cu (s) Ionic equation for the reaction can be written as ; Fe (s) + Cu2+ (aq) → Fe2+ (aq) + Cu (s) In this reaction iron loses two electron and is oxidized to Fe2+ . Fe (s) → Fe2+ (aq) (-2e– ) (Oxidation) On the other hand Cu2+ gains two electrons and is reduced to copper. Cu2+ (aq) → 2e– → Cu (s) (Reduction) Thus the given reaction is a redox reaction. |
