During electroplating, where is the object placed, which needs to be coated with a metallic layer?

Options

A. Electrolyte
B. Cathode
C. Anode
D. Both (a) and ( c )

Answer

To answer the question "During electroplating, where is the object placed which needs to be coated with a metallic layer?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand Electroplating**: Electroplating is a process where a metal layer is deposited onto a surface using electrical energy. This is done to enhance the appearance, prevent corrosion, or improve wear resistance.

2. **Identify the Components**: In an electroplating setup, there are typically three main components:
- **Electrolyte**: An aqueous solution that conducts electricity and contains metal ions.
- **Anode**: The electrode where oxidation occurs. This is typically where the metal to be plated (e.g., zinc) is placed.
- **Cathode**: The electrode where reduction occurs. This is where the object that needs to be coated is placed.

3. **Placement of the Object**: The object that needs to be coated with a metallic layer is placed at the **cathode**. This is because the cathode attracts cations from the electrolyte, which will deposit onto the surface of the object.

4. **Conclusion**: Therefore, during electroplating, the object that requires a metallic coating is placed at the cathode.

### Final Answer:
The object that needs to be coated with a metallic layer is placed at the **cathode** during electroplating.
