Solutions

1. Solutions

2. Suspension • A mixture in which particles can be seen and easily separated by settling or filtration.

3. Solutions • Water and table salt form a solution, a well-mixed mixture. If you taste a salt solution, any sip tastes just as salty as the next.

4. Solvents and Solutes • All solutions have at least two parts: the solvent and the solute. • The solvent is the part of a solution present in the largest amount. It dissolves the other substances. • The solute is the substance that dissolves in the solvent. • In many common solutions, the solvent is water.

5. Examples of Common Solutions

6. Solubility • A measure of how well a solute can dissolve in a solvent at a given temperature. • When you’ve added so much solute that no more dissolves, you have a saturated solution. • If you can continue to dissolve more solute, you still have an unsaturated solution.

7. Solubility Continued • The solubility of a substance tells you the limit on how much you can add before you make a saturated solution.

8. Strips • Which of the following is a homogenous mixture? • Tossed Salad • Soil • Salt water • Vegetable soup

9. 2. If the label on a bottle of medicine reads “shake well before using,” the medicine is probably a a. solution b. suspension c. colloid d. gel

10. Suppose you add a teaspoon of table salt to a cool saltwater solution and stir until all of the salt dissolves. The solution you started with was • Unsaturated • Supersaturated • Saturated • Concentrated

11. Which of the following materials is an example of a solid dissolved in another solid? a. smoke b. bronze c. mayonnaise d. ice
