The potential differnce between the fixed particles layer and the diffused layer having opposite charge id called :

Options

A. Zeta potential
B. Colloidal potential
C. Dorn potential
D. Streaming potential

Explanation

To solve the question, we need to understand the concept of the potential difference between the fixed particle layer and the diffused layer in the context of charged particles in a colloidal system.

### Step-by-Step Solution:

1. **Understanding the Charged Particle System**:
- When a charged particle (for example, a negatively charged solute particle) is present in a solution, it attracts oppositely charged ions from the surrounding medium.

2. **Formation of the Stern Layer**:
...
