Homogeneous Mixtures

A homogeneous mixture is a type of mixture where the parts are evenly mixed, and you cannot see the different substances in it. It looks the same all throughout.

Examples:

Salt dissolved in water

Air (a mixture of gases)

Milk (a well-mixed liquid)

Key Features:

Looks like one single substance

You can’t see the parts

The composition is the same throughout

1. Heterogeneous and Homogeneous Mixture

2. Homogeneous Heterogeneous Mixtures can be:

3. HOMOGENEOUS MIXTURES -Large enough to be seen and are e asier to be separated. - Individual substances that constitute a homogeneous mixture cannot be visually differentiated. 

4. HETEROGENEOUS MIXTURE

5. HETEROGENEOUS MIXTURES -Have components that can be separated manually. -Nonuniform in composition. -Components may vary in amount.

6. SUSPENSION

7. To be effective, always shake a SUSPENSION medicine f irst before administering it to get its full medical s treng th.

8. WHAT IS COLLOID?

9. COLLOID - Has properties that are between h omogeneous and heterogeneous mixtures.
