the substance present in the larger amount (what you're

dissolving in)

TERM 7

aqueous solution

DEFINITION 7

solution with water as the solvent

TERM 8

electrolyte

DEFINITION 8

substance that conducts an electric current with water

TERM 9

nonelectrolyte

DEFINITION 9

poor conductor of electricity

TERM 10

solubility

DEFINITION 10

the amount of a solute that dissolves in a given amount

Henry's law

the solubility of a gas in a liquid is proportional to the partial

pressure of the gas above the liquid

TERM 17

the higher the pressure, the ___ the solubility

of gas in a solvent

DEFINITION 17

higher

TERM 18

DEFINITION 18

how much solute is dissolved in a given amount of solution

TERM 19

DEFINITION 19

the number of grams of solute dissolved in 100 mL of

solutionmass of solute (g) x 100volume of solution (mL)

TERM 20

solventvolume of solute (mL) x 100volume of solution (mL)

parts per million

mass of solute (g) x 10^6mass of solution (g)volume of

solute (mL) x 10^6volume of solution (mL)

TERM 22

Molarity

DEFINITION 22

moles of solute (mols) liters of solution (L)

TERM 23

dilution

DEFINITION 23

the addition of solvent to decrease the concentration of the

solution

TERM 24

colligative properties

DEFINITION 24

properties of a solution that depend on the concentration of

the solute but not its identity

TERM 25

volatile

DEFINITION 25

a solute that readily escapes into the vapor phase

the amount by which the freezing point is

depressed depends on

the number of dissolved particles

TERM 32

osmosis

DEFINITION 32

semipermeable membrane from low to high concentration

TERM 33

semipermeable membrane

DEFINITION 33

a membrane that allows water and small molecules to pass

across, but ions and large molecules can not

TERM 34

osmotic pressure

DEFINITION 34

the pressure that prevents the flow of additional solvent into

a solution on one side of a semipermeable membrane

TERM 35

DEFINITION 38

two solutions with the same osmotic pressure

TERM 39

dialysis

DEFINITION 39

the process that involves selective passage of a substance

across a semipermeable membrane
