Which of the following statements are correct with reference to the following reaction? (A) The reduction reaction is $ \text{Cu}^{2+}(aq)+2e^{-}\rightarrow\text{Cu}(s) $ Choose the correct answer from the options given below: |
(A), (B) and (C) only (A), (B) and (D) only (A), (B), (C) and (D) (B), (C) and (D) only |
(A), (B) and (C) only |
The correct answer is Option (1) → (A), (B) and (C) only $ \text{Cu}^{2+}+2e^{-}\rightarrow\text{Cu}(s) $ is the reduction half-reaction ($ \text{Cu}^{2+}$ gains electrons). $ \text{Zn}(s)\rightarrow\text{Zn}^{2+}+2e^{-} $ is the oxidation half-reaction ($Zn$ loses electrons). These half-reactions represent the redox couples $\text{Cu}^{2+}/Cu$ and $\text{Zn}^{2+}/Zn$, so together they form the redox process. False — the overall reaction is a classic redox reaction. |
