What is the term for the electrode where oxidation occurs?

Options

A. anode
B. cathode
C. oxidizing agent
D. reducing agent

Answer

To answer the question "What is the term for the electrode where oxidation occurs?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electrodes**: In electrochemical cells, there are two types of electrodes: the anode and the cathode. Each has a specific role in the electrochemical reaction.

2. **Defining Oxidation**: Oxidation is defined as the process in which an atom or ion loses electrons. This is a key concept in redox (reduction-oxidation) reactions.

3. **Identifying the Anode**: The anode is the electrode where oxidation occurs. It is typically the positive electrode in an electrolytic cell, where the oxidation reaction takes place.

4. **Example of Electrolysis**: For instance, in the electrolysis of sodium chloride (NaCl), the chloride ions (Cl⁻) move towards the anode. At the anode, these ions lose electrons (oxidation) to form chlorine gas (Cl₂).

5. **Conclusion**: Therefore, the term for the electrode where oxidation occurs is the **anode**.

### Final Answer:
The term for the electrode where oxidation occurs is the **anode**.
