Colloidal solutions form homogeneous/heterogeneous mixtures

Explanation

To determine whether colloidal solutions form homogeneous or heterogeneous mixtures, we can analyze the properties of colloids in relation to solutions and suspensions.

### Step-by-Step Solution:

1. **Definition of Colloids**:
- A colloid is a type of mixture where very small particles of one substance are dispersed throughout another substance. These particles are larger than those in a true solution but smaller than those in a suspension.

2. **Comparison with Solutions and Suspensions**:
