Options

A. Tyndall effect
B. Coagulation
C. Electrophoresis
D. Electro-osmosis

Answer

To determine which property of a colloidal solution is independent of the charge on the colloidal particles, we can analyze the properties of colloids and their behavior.

### Step-by-Step Solution:

1. **Understanding Colloidal Solutions**:
- Colloidal solutions consist of tiny particles (colloids) dispersed in a medium. These particles can carry a positive or negative charge depending on the nature of the colloid and the medium.

2. **Identifying Properties of Colloids**:
- Several properties are associated with colloidal solutions, including:
- Tyndall effect
- Coagulation
- Electrophoresis
- Electroosmosis

3. **Analyzing Each Property**:
- **Tyndall Effect**: This is the scattering of light by colloidal particles, making them visible when light passes through the solution. It occurs regardless of whether the particles are positively or negatively charged. Thus, the Tyndall effect is independent of the charge on the colloidal particles.

- **Coagulation**: This process involves the aggregation of colloidal particles, leading to the formation of a precipitate. Coagulation is influenced by the charge on the particles, as opposite charges attract and neutralize each other, leading to aggregation.

- **Electrophoresis**: This refers to the movement of charged colloidal particles in an electric field. The direction and speed of movement depend on the charge of the particles, making this property charge-dependent.

- **Electroosmosis**: This involves the movement of liquid through a porous medium under the influence of an electric field, which also depends on the charge of the particles.

4. **Conclusion**:
- Among the properties analyzed, the **Tyndall effect** is the only property that does not depend on the charge of the colloidal particles. Therefore, the correct answer to the question is the Tyndall effect.

### Final Answer:
The property of colloidal solution that is independent of the charge on the colloidal particles is the **Tyndall effect**.
