The electrode connected to positive terminal of the battery is called _____

Options

A. Cathode
B. Anode
C. Electrode
D. None of these

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks for the name of the electrode that is connected to the positive terminal of a battery.

2. **Identifying the Electrode**: In electrochemical processes, electrodes play a crucial role. The electrode connected to the positive terminal of the battery is known as the anode.

3. **Role of the Anode**: The anode is where oxidation occurs. This means that during the electrochemical reaction, the species at the anode loses electrons.

4. **Electrolysis Context**: In the context of electrolysis, there are two electrodes: the anode and the cathode. The anode is connected to the positive terminal of the battery, while the cathode is connected to the negative terminal.

5. **Movement of Ions**: In an electrolytic solution, negative ions (anions) migrate towards the anode (positive terminal) where oxidation occurs, while positive ions (cations) move towards the cathode (negative terminal) where reduction takes place.

6. **Example with NaCl**: Taking molten sodium chloride (NaCl) as an example, when it is electrolyzed, chloride ions (Cl⁻) move towards the anode and get oxidized to form chlorine gas (Cl₂), while sodium ions (Na⁺) move towards the cathode and get reduced.

7. **Conclusion**: Therefore, the electrode connected to the positive terminal of the battery is called the anode, where oxidation occurs.

**Final Answer**: The electrode connected to the positive terminal of the battery is called the **anode**.
