Questions and Answers
- 1.
A solvent is...
- A.
A solution
- B.
What the solvent is disolved in.
- C.
Is always water.
- D.
Can be a solid.
- E.
B and D
Correct Answer
E. B and DExplanation
A solvent is a substance that is capable of dissolving other substances, known as solutes. It is a solution in which the solute is dissolved. The solvent can be a liquid, such as water, or even a solid. Therefore, the correct answer is B and D, as both options state that a solvent can be dissolved in something else and can be a solid.Rate this question:

What type of mixture is a solution?
- A.
Heterogeneous
- B.
Homogeneous
- C.
Immiscible
- D.
All of the above
Correct Answer
B. HomogeneousExplanation
A solution is a type of mixture that is homogeneous, meaning that it has a uniform composition throughout. In a solution, the solute particles are evenly distributed and dissolved in the solvent, resulting in a single phase with no visible boundaries or separation. This is in contrast to a heterogeneous mixture, where the components are not evenly distributed and can be seen as separate phases. Immiscible refers to substances that cannot be mixed together to form a homogeneous solution. Therefore, the correct answer is "Homogeneous."Rate this question:

What is the term that describes the dissolving process?
- A.
Saturation
- B.
Solubulity
- C.
Solvation
- D.
None
Correct Answer
C. SolvationExplanation
Solvation is the correct answer because it refers to the process of dissolving a solute in a solvent, resulting in the formation of a homogeneous solution. During solvation, the solvent molecules surround and interact with the solute particles, breaking their intermolecular forces and allowing the solute to become dispersed throughout the solvent. This process is essential in various chemical and biological reactions and is influenced by factors such as temperature, pressure, and the nature of the solute and solvent.Rate this question:

When two liquids mix, they are said to be...
- A.
Soluble
- B.
Miscible
- C.
Solution
- D.
Solvent
Correct Answer
B. MiscibleExplanation
When two liquids are able to mix together in all proportions and form a homogeneous mixture, they are said to be miscible. This means that the molecules of the two liquids are able to intermingle and form a uniform solution. Soluble refers to the ability of a substance to dissolve in a solvent, while solution refers to the homogeneous mixture formed when a solute is dissolved in a solvent. Solvent refers to the substance in which a solute is dissolved.Rate this question:

Which way is NOT a way to increase the rate of solvation?
- A.
Agitation
- B.
Increased temperature
- C.
increased surface area
- D.
Cooling
Correct Answer
D. CoolingExplanation
Cooling is not a way to increase the rate of solvation because it actually slows down the process. When a solution is cooled, the molecules move slower and have less kinetic energy, making it more difficult for solute particles to dissolve in the solvent. On the other hand, agitation, increased temperature, and increased surface area all promote solvation by providing more opportunities for solute particles to come into contact with the solvent and dissolve.Rate this question:

Solubility is the term that describes the ability of a substance to dissolve at particular temperatures. Solubility is expressed as grams of solute per ______________ grams of solvent.
- A.
10
- B.
50
- C.
100
- D.
200
Correct Answer
C. 100Explanation
Solubility is expressed as grams of solute per 100 grams of solvent. This means that for every 100 grams of solvent, a certain amount of solute can dissolve. The ratio of solute to solvent is important in determining the solubility of a substance.Rate this question:

What does it mean when a solution is unsaturated?
- A.
Too much solute
- B.
Not enough solute
- C.
Just enough solute
- D.
None
Correct Answer
B. Not enough soluteExplanation
When a solution is unsaturated, it means that there is not enough solute dissolved in the solvent. In other words, the solution has the capacity to dissolve more solute. This is in contrast to a saturated solution, where the maximum amount of solute has been dissolved and any additional solute will not dissolve.Rate this question:

What does it mean when a solution is supersaturated?
- A.
Too much solute
- B.
Not enough solute
- C.
just enough solute
- D.
None
Correct Answer
A. Too much soluteExplanation
When a solution is supersaturated, it means that there is an excess amount of solute dissolved in the solvent. This occurs when the solution is prepared at a higher temperature and then gradually cooled down, allowing more solute to dissolve than would normally be possible at that temperature. As a result, the solution becomes unstable and can easily precipitate or form crystals if disturbed.Rate this question:

Insoluble means that two substances can dissolve in one another.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Insoluble means that two substances cannot dissolve in one another. Therefore, the correct answer is False.Rate this question:

In a solution containing water and polar solute particles _____
- A.
The polar particles will disperse randomly throughout the water
- B.
He polar particles form ionic bonds with water molecules
- C.
The polar particles will not dissolve
- D.
Hydrogen bonding allows the particles to dissolve
Correct Answer
D. Hydrogen bonding allows the particles to dissolveExplanation
In a solution containing water and polar solute particles, hydrogen bonding allows the particles to dissolve. Hydrogen bonding is a strong intermolecular force that occurs between the positive hydrogen atom of one water molecule and the negative oxygen atom of another water molecule. This bonding allows water molecules to surround and solvate the polar solute particles, breaking them apart and dispersing them randomly throughout the water. This process is essential for the dissolution of polar solutes in water.Rate this question:
