Understanding Oxidation and Reduction
In the given reaction, we need to identify which substances are oxidised and reduced.
Reaction Breakdown:
CuO(s) + Zn(s) → Cu(s) + ZnO(s)
Oxidation and Reduction Definitions:
- Oxidation: Loss of electrons or an increase in oxidation state.
- Reduction: Gain of electrons or a decrease in oxidation state.
Analyzing the Reactants and Products:
- Copper(II) oxide (CuO): In CuO, copper is in the +2 oxidation state. When it becomes copper metal (Cu), its oxidation state drops to 0, indicating that CuO is reduced.
- Zinc (Zn): Zinc starts in the elemental state (0 oxidation state) and transforms into zinc oxide (ZnO), where zinc has a +2 oxidation state. This implies that zinc has lost electrons, indicating oxidation.
Conclusion:
- CuO is reduced: It accepts electrons and its oxidation state decreases from +2 to 0.
- Zn is oxidised: It loses electrons and its oxidation state increases from 0 to +2.
Thus, the correct answer is:
Option A: CuO-reduced and Zn-oxidised
