Electroplating is based on :

Options

A. Magnetic effect of electricity
B. Chemical effect of electricity
C. Heating effect of electricity
D. Physical effect of electricity

Answer

To answer the question "Electroplating is based on:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electroplating**: Electroplating is a process where a layer of metal is deposited onto a surface through the use of electric current. This process involves the movement of ions in a solution.

2. **Identifying the Components**: In electroplating, there are two electrodes (anode and cathode) and an electrolyte solution that contains metal ions. The electrodes are connected to a power source.

3. **Role of Electric Current**: When electric current passes through the electrolyte, it causes the metal ions to move towards the cathode (negative electrode) where they gain electrons and get reduced to form a solid metal layer.

4. **Chemical Effects of Electricity**: The process of electroplating is fundamentally a chemical reaction facilitated by electricity. The electric current causes the ions in the solution to undergo chemical changes, leading to the deposition of metal.

5. **Conclusion**: Therefore, electroplating is based on the **chemical effect of electricity**.

### Final Answer:
Electroplating is based on the **chemical effect of electricity**.
