2. Homogeneous Mixtures Versus Heterogeneous Mixtures
MS7.1
Distinguish between pure substances and mixtures (mechanical mixtures and solutions) using the particle model of matter

4. Homogeneous Mixtures or Solutions
Solution is a solute that is dissolved in a solvent
The mixture is not always visible after being mixed together
For example:
In pudding, you cannot see the powdered chocolate mixed in milk after the homogeneous mixture or
solution is mixed

5. Parts of a Solution (Homogeneous Mixture)
Solute – the part of a solution that is being dissolved (usually the lesser amount)
Solvent – the part of a solution that dissolves the solute (usually the greater amount)
Remember:
solute + solvent = solution

6. What is the difference between solutions and homogeneous mixtures?

7. What is the solute and the solvent in this homogeneous mixture or solution?

8. Heterogeneous (Mechanical) Mixture
You can see the different items after it is still all mixed together

9. WE INTERRUPT THIS FOODIE SLIDESHOW TO BRING TO YOU AN IMPORTANT ENVIRONMENTAL MESSAGE

10. You can get suspensions from heterogeneous mixtures.

11. Oil and water are heterogeneous mixtures that create a suspension because they refuse to mix.

12. Heterogeneous Mixtures/ Suspension Oil Spill Disaster
Valdez, Alaska 1989

13. This spill created a suspension too.
You can see the oil settling on top of the water. If you can see the two or more items being mixed, it is a heterogeneous mixture.
Gulf of Mexico (Caribbean), 2010

14. More suspension oil spills…

15. What is the difference between a heterogeneous mixture and a mechanical mixture?

16. Which one is NOT heterogeneous or a mechanical mixture?

17. Did you know????
Homo means “the same”
Hetero means “different”
