Stenberg Chemistry Ch 14

Front 1

boiling-point elevation

Back 1

the difference between the boiling points of the pure solvent and a solution of a nonelectrolyte in that solvent

Front 2

colligative properties

Back 2

properties that depend on the concentration of solute particles but not on their identity

Front 3

dissociation

Back 3

the separation of ions that occurs when an ionic compound dissolves

Front 4

freezing-point depression

Back 4

the difference between the freezing points of the pure solvent and a solution of a nonelectrolyte in that solvent

Front 5

hydronium ion

Back 5

H3O+

Front 6

ionization

Back 6

ions are formed from solute molecules by the action of the solvent

Front 7

molal boiling-point constant

Back 7

the boiling-point elevation of the solvent in a 1-molal solution of a nonvolatile, nonelectrolyte solute

Front 8

molal freezing-point constant

Back 8

the freezing-point depression of the solvent in a 1-molal solution of a nonvolatile, nonelectrolyte solute

Front 9

net ionic equation

Back 9

An equation that includes only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution

Front 10

nonvolatile substance

Back 10

a substance that has little tendency to become a gas under existing conditions

Front 11

osmosis

Back 11

The movement of solvent through a semipermeable membrane from the side of lower solute concentration to the side of higher solute concentration

Front 12

osmotic pressure

Back 12

the pressure required to stop the process of osmosis

Front 13

semipermeable membrane

Back 13

a barrier that allows some substances to pass through while preventing the movement of others

Front 14

spectator ions

Back 14

ions that do not undergo a chemical change when a reaction occurs in an aqueous solution

Front 15

strong electrolyte

Back 15

a compound of which all or almost all of the dissolved compound exists as ions in an aqueous solution

Front 16

weak electrolyte

Back 16

a compound of which a relatively small amount of the dissolved compound exists as ions in an aqueous solution
