Migration of colloidal particles under the influence of electrie field is known as…………………

Options

A. Electrophoresis
B. Dialysis
C. lonisation
D. Electrodialysis

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the migration of colloidal particles when an electric field is applied. We need to identify the specific term that describes this phenomenon.

2. **Identifying Key Terms**: The key terms in the question are "migration," "colloidal particles," and "electric field." These terms suggest a process involving charged particles moving in response to an electric potential.

3. **Analyzing Options**: The options provided are:
- A) Electrophoresis
- B) Dialysis
- C) Ionization
- D) Electrodialysis

4. **Defining Each Option**:
- **Electrophoresis**: This is the process where charged particles move under the influence of an electric field.
- **Dialysis**: This is a separation process that involves the movement of solutes through a semipermeable membrane, not necessarily under an electric field.
- **Ionization**: This refers to the process of forming ions from neutral atoms or molecules, not directly related to movement in an electric field.
- **Electrodialysis**: This involves the movement of ions through selective ion-exchange membranes under an electric field, but it is not specifically about colloidal particles.

5. **Selecting the Correct Answer**: Based on the definitions, the correct term for the migration of colloidal particles under the influence of an electric field is **Electrophoresis** (Option A).

6. **Conclusion**: Therefore, the migration of colloidal particles under the influence of an electric field is known as **Electrophoresis**.
