This document compares and contrasts solutions, suspensions, and colloids. It defines each type of mixture and provides examples. Solutions have dissolved particles that do not separate or scatter light, while suspensions are heterogeneous mixtures with insoluble particles that settle out and can be filtered. Colloids have properties of both solutions and suspensions, with small particles that do not dissolve and cannot be separated by filtering. The document gives examples like milk and blood plasma to illustrate colloids.

1. Heterogeneous Mixtures December 3, 2009 We are using the clickers today!

2. Objectives Compare and contrast a solution, suspension and a colloid Describe and give examples of suspensions and colloids

4. Solutions Have dissolved particles Do not separate Cannot be filtered Do not scatter light

5. The individual components of a mixture are present in similar amounts regular amounts fixed amounts different amounts

6. Which of the following is a homogeneous mixture? fruit salad kool aide chocolate chip cookie a bowl of yogurt and fruit

7. What is considered to be the universal solvent?

8. Suspensions A heterogeneous mixture in which particles of the material are dispersed throughout a liquid or gas. The particles in a suspension are insoluble, so they settle out. Can be separated by passing them through a filter.

9. Examples of Suspensions Snow globes Muddy water Salad dressing Paint

10. Colloids A colloid is a mixture that has the properties of both a solution and a suspension.

11. Colloids Particles are small but do not dissolve Mixture can not be separated by passing them through a filter.

12. The particles in a suspension are _________ than the particles in a colloid. a. larger b. smaller c. more soluble d. less soluble

14. Tyndall effect Colloidal suspensions can scatter rays of light.

16. How are colloids similar to solutions? Both are mixtures Both contain dissolved solutes Both can be separated Both scatter beams of light

17. Examples of Colloids Fog Whipped cream Milk Cheese Blood plasma Jell-o

18. If the label on a medicine bottle says "shake well before using", the medicine is probably a solution suspension colloid compound
