In dialysis, colloidal particles are separated from

Options

A. Solvent
B. Dispersed phase
C. Ions electrolytes
D. Particles of dispersion medium

Explanation

To solve the question regarding dialysis and the separation of colloidal particles, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Dialysis**:
- Dialysis is a process used to separate small solute particles from larger colloidal particles. It involves the use of a semipermeable membrane that allows certain particles to pass through while blocking others.

2. **Identifying the Components**:
- In dialysis, we are dealing with two main components: colloidal particles (which are larger) and dissolved ions or molecules (which are smaller).

3. **Mechanism of Separation**:
- The separation occurs due to the unequal rate of diffusion through the semipermeable membrane. Colloidal particles cannot pass through the membrane, while smaller dissolved ions and molecules can.

4. **Conclusion**:
- Therefore, in dialysis, colloidal particles are separated from dissolved ions or molecules.

5. **Final Answer**:
- The correct option is that colloidal particles are separated from dissolved ions or molecules.
