Question and Answer
1. Solution is formed when *
C. solutes dissolved in solvent
Explanation
A solution is made when one substance called the solute "dissolves" into another substance called the solvent.
Question and Answer
2. A solution that contains less solute than the maximum amount it can dissolved at a given temperature. *
D. Unsaturated Solution
Explanation
A solution that contains less solute than can dissolve at a given temperature is called an unsaturated solution.
Question and Answer
3. The solution that contains the maximum amount of solute dissolved by a given amount of solvent is called _____ *
C. Saturated Solution
Explanation
Solution which contains maximum possible amount of solute at any given temperature is called a saturated solution.
4. Something that can be dissolved in a solution is called ______. *
Question and Answer
B. Soluble
Explanation
In the process of dissolving, the substance which is being dissolved is called a solute and the substance in which the solute is dissolved is called a solvent.
Question and Answer
5. The substance that gets dissolved is called the________ *
A. Solute
Explanation
A solution is a mixture of two or more homogeneous substances where the dissolved substance is known as solute and the substance in which the solute get dissolved is known as a solvent.
Question and Answer
6. Water is an example of a ___________ *
D. Saturated
Explanation
A saturated solution is one where there are about equal amounts of particles or solutes and solvent in the solution
Question and Answer
7. What is the solution that contains more solute than a saturated solution under the same conditions? *
D. Supersaturated
Explanation
Saturated Solution is a solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom, whereas, Supersaturated Solution is a solution (with more solute than the saturated solution) that contains more undissolved solute than the saturated solution because of its tendency to crystallize and precipitate.
Question and Answer
8. Which of the following is not an example of a solution? *
D. Oil in Water
Explanation
Oil and water is a mixture, not a solution. The two types of molecules (oil and water) are not evenly distributed in the system.
Question and Answer
9. Which of the following is an example of a solution? *
A. Vinegar
B. Orange Juice
C. Soy Sauce
D. Oil in Water
Explanation
Vinegar - Solution of Liquid in a Liquid: Vinegar is a solution of acetic acid in water. It is liquid in liquid type of solution.
Orange juice - A homogeneous mixture often called as solution, orange juice is a solution without pulp, uniformly distributed throughout the mixture.
Soy Sauce - Soy sauce is a condiment made from a fermented paste of boiled soybeans, roasted grain, brine (solution of salt in water), and Aspergillus oryzae or Aspergillus sojae molds. Therefore, water is the main solute in soy sauce
Question and Answer
10. Hannah made a pitcher of lemonade. What can she do to dilute if she thinks it doesn’t taste right? *
B. add sugar
Explanation
Hannah can add some sugar to her lemonade because sugar will help her get a better taste of a lemonade.
Question and Answer
11. When a solution is saturated? *
A. crystals form
Explanation
The solution is said to be saturated if the rate of crystallization and the rate of solubility are the same.
Question and Answer
12. How will you prepare an unsaturated solution? *
D. Add more amount of solute in a lower amount of solvent
Explanation
For the formation of a solution, we need to add a solute to a solvent. Initially, the solute dissolves in a solvent and makes a uniform solution. Such a solution where solutes dissolve is called an unsaturated solution. Basically, a solution comprises two different kinds of particles, solutes and the solvent.
Question and Answer
13. Why increasing temperature of the solvent will speed up the dissolving process? Because it brings __________________________. *
D. more solvent molecules to collide with the solute
Explanation
Due to the speed of these molecules, the chances of interaction between solute and solvent molecules increases. This causes an increase in the rate of dissolution and we see that solute dissolves much faster in solvents with higher temperature.
Question and Answer
14. You are given a 40 mL solution in a beaker. You add solute to the beaker and you observed some particles did not dissolve. What solutions is it? *
A. Saturated
Explanation
When it comes to saturated solutions, there is a saturation point that determines the type of solution. For unsaturated solutions, it only means that the dissolved solute is still below the saturation point. More solute can still dissolve in it.
Question and Answer
15. You are given a 30 mL solution in a beaker. You add solute to the beaker and it dissolves completely. What is the solution? *
Explanation
B. Saturated solution
A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved.
