To solve the question regarding the correct option among the given statements about colloidal chemistry, we will analyze each option step by step. ### Step 1: Analyze Option 1 **Statement:** Colloidal particles in lyophobic sols can be precipitated by electrophoresis since lyophobic sols are charged colloidal particles. **Explanation:** - Lyophobic sols consist of particles that do not have a strong affinity for the dispersing medium (solvent). - These particles are typically charged, allowing them to move in an electric field. ...
