Physical Science Chapter 7 Test Review ANSWERS-- Test on THURSDAY

Physical Science Chapter 7 Test Review

1. What is a suspension?
• A liquid mixture in which particles can be seen and easily separated by settling or filtration

2. What is a saturated solution?
• When you add so much solute that no more will dissolve

3. How do we increase the solubility of sugar in water?
• Heat the water

4. How would a solute affect the boiling point of water?
• Raise the boiling point (raise the temperature)

5. How is a solute different from a solvent in a solution?
• The solute is present in a smaller amount

6. How can we safely tell whether an unknown solution contains salt or sugar?
• By testing the electrical conductivity of the solution

7. What would weak tea be an example of?
• Dilute solution

8. What happens to the freezing point of the solution when a solute is added to a solvent?
• Freezing point changes.  It is lower than the freezing temperature of ether substance alone

9. What type of change does an acid make to litmus paper? 
• Acids make blue litmus paper turn red

10.  How do acids differ from bases in water solution?
• Acids produce hydrogen ions (H+) and bases produce hydroxide ions (OH-)

11.  Why are acids considered to be corrosive?
• They “eat away” at other materials

12.  What do bases form in water?
• Hydroxide ions (OH-)

13.  What does the pH scale measure?
• The concentration of hydrogen ions

14.  What is neutralization?
• A reaction between an acid and a base

15.  What does a neutralization reaction produce?
• A salt and water

16.  When a few spoonfuls of sugar are added to a cup of water, what is the sugar?
• The Solute

17.  What happens to a solid compound when it is dissolved in water?
• Each of its particles are surrounded by water molecules

18.  What is solubility?
• The measure of how well a solute can dissolve in a solution at a given temperature

19.  What is a colloid?
• A mixture containing particles that are too small to be seen easily, but are large enough to scatter a light beam

20.  What is a solution?
• A mixture that appears uniform throughout & whose particles cannot easily be seen

21.  What is an unsaturated solution?
• A solution to which you can continue to add solute

22.  What is an acid?
• A compound that tastes sour and reacts with some metals

23.  What is a base?
• A compound that turns litmus blue and is often found in soaps and detergents

24.  What does a high pH tell you?
• The concentration of hydrogen ions is low

25.  What happens to the pH in a neutralization reaction?
• The pH changes to a value that is closer to neural

26.  What is the universal solvent?
• Water

27.  What is a salt?
• An ionic compound produced from the neutralization of an acid and a base

28.  Be able to read a pH chart and use that information to answer questions.  (Sample chart on page 245 in textbook.)

Essay:

29.  Describe how solutions of acids and bases differ in terms of particles.  How do the differences relate to the properties of acids and bases?

30. Describe the differences among solutions, colloids, and suspensions.
