Question 19

Solvent

Answer 19

Is the component of a solution that is present in the greatest amount.

Question 20

Solute

Answer 20

Is a solution component that is present in a small amount relative to that of the solvent.

Question 21

Solubility

Answer 21

Of a solute is the maximum amount of solute that will dissolve in a given amount of solvent.

Question 22

Saturated solution

Answer 22

Is a solution that contains the maximum amount of solute that can be dissolved under the conditions at which the solution exists.

Question 23

Unsaturated solution

Answer 23

Is a solution in which less solute than the maximum amount possible is dissolved in the solution.

Question 24

Concentrated solution

Answer 24

Is a solution that contains a large amount of solute relative to the amount that could dissolve.

Question 25

Aqueous solution

Answer 25

Is a solution in which water is the solvent.

Question 26

Nonaqueous solution

Answer 26

Is a solution in which water is not the solvent.

Question 27

Percent by mass

Answer 27

Percent by mass = mass of solute/ mass of solution x 100

Question 28

Mass solution =?

Answer 28

Mass of solute + mass of solvent

Question 29

Percent by Volume

Answer 29

Is equal to the volume of solute divided by the total volume of solution, multiplied by 100.

Question 30

Percent by volume = ?

Answer 30

Volume of solute/ volume of solution x 100

Question 31

Mass-volume percent

Answer 31

Is equal to the mass of solute (in grams) divided by the total volume of solution (in milliliters), multiplied by 100.

Question 32

Mass volume percent = ?

Answer 32

Mass of solute (g)/ volume of solution (mL) x 100

Question 33

Molarity

Answer 33

Of a solution is a ratio giving the number of moles of solute per liter of solution.

Question 34

Molarity (M)

Answer 34

Moles of solute/ liters of solution

Question 35

Osmosis

Answer 35

Is the passage of a solvent from a dilute solution (or pure solvent) through a semipermeable membrane into a more concentrated solution.

Question 36

Semipermeable membrane

Answer 36

Is a thin layer of material that allows certain types of molecules to pass through but prohibits the passage of others.

Question 37

Isotonic solution

Answer 37

Is a solution whose osmotic pressure is equal to that within cells. Red blood cell fluid, saline solution, and 5% m/v glucose water are isotonic. No effect on cell size.

Question 38

Hypotonic solution

Answer 38

Is a solution with a lower osmotic pressure than that within cells. Distilled water is hypotonic with respect to red blood cell fluid and cells hemolyze.

Question 39

Hypertonic solution

Answer 39

Is a solution with a higher osmotic pressure than that within cells. Causes cells to crenate (shrink).

Question 40

Dialysis

Answer 40

Is the process in which a semipermeable membrane permits the passage of solvent, dissolved ions, and small molecules but blocks the passage of large molecules.
