### Understanding Electrode Polarity in a Zinc-Copper CellIn a zinc-copper cell, represented as:\[ \text{Zn}_{(s)} | \text{Zn}^{+2}_{(aq)} || \text{Cu}^{+2}_{(aq)} | \text{Cu}_{(s)} \]Which electrode is positive?#### Options:- **A.** \( \text{Cu}^{+2} \)- **B.** \( \text{Cu}_{(s)} \)- **C.** \( \text{Zn}_{(s)} \)- **D.** \( \text{Zn}^{+2} \)### Explanation:To understand which electrode is positive in this galvanic cell, we need to examine the standard cell notation and the principles of electrochemistry:1. **Cell Notation:** The notation \( \text{Zn}_{(s)} | \text{Zn}^{+2}_{(aq)} || \text{Cu}^{+2}_{(aq)} | \text{Cu}_{(s)} \) represents a galvanic cell where zinc metal is oxidized to zinc ions \((\text{Zn}^{+2})\), and copper ions \((\text{Cu}^{+2})\) are reduced to copper metal. 2. **Oxidation and Reduction:** - Oxidation occurs at the anode: \( \text{Zn}_{(s)} \rightarrow \text{Zn}^{+2}_{(aq)} + 2e^- \) - Reduction occurs at the cathode: \( \text{Cu}^{+2}_{(aq)} + 2e^- \rightarrow \text{Cu}_{(s)} \)3. **Electrode Polarity:** - In a galvanic cell, the anode (where oxidation occurs) is negative. - The cathode (where reduction occurs) is positive.Therefore, in the given zinc-copper cell, \( \text{Cu}_{(s)} \) (the copper solid electrode) is the positive electrode, because it is where the copper ions \((\text{Cu}^{+2})\) gain electrons (reduction) to form solid copper.### Correct Answer:**B.** \( \text{Cu}_{(s)} \)
