What is the difference between multimolecular and macromolecular collids ? Give one example of each . How are associated colloids different from these two types of colloids ?

Explanation

### Step-by-Step Solution:

1. **Definition of Multimolecular Colloids**:
- Multimolecular colloids are formed by the aggregation of small molecules. These molecules typically have a diameter of less than 1 nanometer.
- **Example**: An example of a multimolecular colloid is a colloidal solution of sulfur or a colloidal solution of silver.

2. **Characteristics of Multimolecular Colloids**:
- These colloids are generally lyophobic, meaning they do not have an affinity for the dispersion medium (usually water). They tend to be unstable and can easily precipitate out of the solution.
