A: Anode is positive electrode and cathode is negative electrode in electrolytic cell.
R: Anode is negative electrode and cathode is positive electrode in electrochemical cell.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1)
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2)
C. If Assertion is true statement but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements then mark (4)

Answer

To analyze the given statements, we need to understand the definitions and characteristics of anodes and cathodes in both electrolytic cells and electrochemical (galvanic) cells.

### Step-by-Step Solution:

1. **Identify the Types of Cells**:
- There are two main types of electrochemical cells: **Electrolytic Cells** and **Electrochemical (Galvanic) Cells**.

2. **Understand the Charge of Electrodes**:
- In an **Electrolytic Cell**:
- The **anode** is the positive electrode.
- The **cathode** is the negative electrode.
- In an **Electrochemical (Galvanic) Cell**:
- The **anode** is the negative electrode.
- The **cathode** is the positive electrode.

3. **Determine the Processes at Each Electrode**:
- In both types of cells, oxidation occurs at the anode (loss of electrons) and reduction occurs at the cathode (gain of electrons).
- In an electrolytic cell, an external power source is required to drive the non-spontaneous reaction.
- In an electrochemical cell, the reaction is spontaneous and generates electrical energy.

4. **Evaluate the Assertion and Reason**:
- **Assertion (A)**: "Anode is positive electrode and cathode is negative electrode in electrolytic cell." - This statement is **true**.
- **Reason (R)**: "Anode is negative electrode and cathode is positive electrode in electrochemical cell." - This statement is also **true**.
- However, the reason does not explain the assertion directly; it simply states a fact about a different type of cell.

5. **Conclusion**:
- Both the assertion and reason are true, but the reason is not the correct explanation for the assertion. Therefore, the correct answer is that both statements are true, but the reason does not adequately explain the assertion.

### Final Answer:
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
