Which of the following is not a property of colloidal solution?

Options

A. Heterogenceity
B. Particle size `gt` 1000 nm
C. Tyndall effect
D. Brownian movement

Explanation

To determine which of the following is not a property of a colloidal solution, we need to analyze the properties associated with colloids. Here’s a step-by-step breakdown of the solution:

### Step 1: Understanding Colloidal Solutions
Colloidal solutions are mixtures where tiny particles (colloids) are dispersed throughout a medium (liquid, gas, or solid). These particles are larger than molecules but smaller than those in a suspension.

**Hint:** Recall that colloids are a type of heterogeneous mixture.
