Peptizing agent is

Options

A. Always an electrolyte
B. Always a non-electrolyte
C. Electrolyte or non-electrolyte
D. A lyophilic colloid

Explanation

**Step-by-Step Solution:**

1. **Definition of Peptizing Agent**: A peptizing agent is a substance that helps in the conversion of a precipitate into a colloidal solution. This process is known as peptization.

2. **Role of Electrolytes**: Peptizing agents are typically electrolytes. Electrolytes are substances that dissociate into ions when dissolved in water, which helps to stabilize the colloidal solution.

3. **Mechanism of Peptization**: When a freshly precipitated solid is treated with a suitable electrolyte, the ions from the electrolyte interact with the surface of the precipitate. This interaction leads to the dispersion of the precipitate into smaller particles, forming a stable colloidal solution.

4. **Conclusion**: Therefore, a peptizing agent is always an electrolyte, as it is essential for the stabilization of the colloidal solution formed from the precipitate.

**Final Answer**: A peptizing agent is always an electrolyte.
