Questions and Answers

1.

A solution is defined as a mixture that is...
- A.
  
  Homologous
- B.
  
  Heterogeneous
- C.
  
  Homogeneous
Correct Answer
C. Homogeneous

Explanation
Solutions are defined as homogeneous mixtures. All of the particles are evenly distributed throughout the mixture. Solutions are usually made of liquids but can also be gases, solids, and gases dissolved in liquids.

2.

Which of these is a solution?
- A.
  
  14K gold
- B.
  
  Salt water
- C.
  
  Carbonated water
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
All of the available choices are solutions. The tricky one might have been the gold choice. 14-karat gold is actually made with multiple metals. The metals are mixed in solutions at very high temperatures. When they cool to a solid form, the solid is defined as a solid solution. Most metal alloys begin their lives as solutions.

Colloids are solutions with very small particles suspended in a liquid.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Colloids are a special type of solution with very small particles suspended within the solvent. Colloid solutions are also called colloidal dispersions.

4.

Small particles remain in colloidal dispersion (colloids) because of...
- A.
  
  Equal molecular weight
- B.
  
  Electrical charges
- C.
  
  Vigorous stirring
- D.
  
  None of the above
Correct Answer
B. Electrical charges

Explanation
Scientists believe that electrical charges hold the small particles in solution. You may find very small pieces of clay suspended in water that never settle. Clay remains suspended because of the electrical attractions between the water molecules.

5.

The concentration of solutions is directly related to...
- A.
  
  Solubility
- B.
  
  Temperature
- C.
  
  Pressure
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
All of the factors can affect the concentration of solutes dissolved in the solvent. Solubility is a characteristic of the solvent. Temperature and pressure are outside influences.

6.

The most common solvent of Earth is...
- A.
  
  Gasoline
- B.
  
  Water
- C.
  
  Turpentine
- D.
  
  None of the above
Correct Answer
B. Water

Explanation
Water (H2O) is the most common solvent on Earth. Solutes are dissolved in solvents.
Water is the "universal solvent".

7.

An increase in pressure can lead to an increase in dissolved gases.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
As the pressure of a system increases, it is easier to dissolve more gases into a liquid. Pressure forces more of the gas molecules into the solvent.
