Given below is a redox reaction. Which of the following types the reaction belong to? \( \boldsymbol{C u}^{+\mathbf{2 + 6 - 2}} \boldsymbol{O}_{4(a q)}+\boldsymbol{Z} \boldsymbol{n}_{(s)} \rightarrow \boldsymbol{C u}_{(s)}+ \) \( \underset{Z n S O_{4(a q)}}{+2+6+-2} \)
- A. Combination reaction
- B. Decomposition reaction
- C. Metal displacement reaction
- D. Non-metal displacement reaction
Step-by-step solution
The reaction is CuSO₄(aq) + Zn(s) → Cu(s) + ZnSO₄(aq). Here, zinc (Zn) displaces copper (Cu) from its salt solution because zinc is more reactive than copper. This is a single displacement reaction involving a metal (Zn) displacing another metal (Cu), hence it is a metal displacement reaction. It is also a redox reaction: Zn is oxidized to Zn²⁺ and Cu²⁺ is reduced to Cu.
