Which of the following statement about galvanic cell is incorrect

Options

A. Anode is positive
B. Oxidation occurs at the electrode with lower reduction potential
C. Cathode is positive
D. Reduction occurs at cathode

Explanation

To determine which statement about a galvanic cell is incorrect, we need to analyze each of the provided options based on the principles of electrochemistry.

### Step 1: Understand the Definitions
1. **Anode**: The electrode where oxidation occurs. In a galvanic cell, the anode is negatively charged.
2. **Cathode**: The electrode where reduction occurs. In a galvanic cell, the cathode is positively charged.
3. **Oxidation**: The loss of electrons.
4. **Reduction**: The gain of electrons.
5. **Reduction Potential**: A measure of the tendency of a chemical species to acquire electrons and be reduced.

### Step 2: Analyze Each Statement
1. **Anode is positive**: This statement is **incorrect**. In a galvanic cell, the anode is negatively charged.
2. **Oxidation occurs at the electrode with lower reduction potential**: This statement is **correct**. Oxidation occurs at the anode, which has a lower reduction potential compared to the cathode.
3. **Cathode is positive**: This statement is **correct**. The cathode is positively charged in a galvanic cell.
4. **Reduction occurs at cathode**: This statement is **correct**. Reduction occurs at the cathode by gaining electrons.

### Step 3: Conclusion
From the analysis, the statement that is incorrect is: **"Anode is positive."**

### Final Answer
The incorrect statement about the galvanic cell is: **"Anode is positive."**
