boiling-point elevation
|
the difference between the boiling points of the pure solvent and a solution of a nonelectrolyte in that solvent
|
|
colligative properties
|
properties that depend on the concentration of solute particles but not on their identity
|
|
dissociation
|
the separation of ions that occurs when an ionic compound dissolves
|
|
freezing-point depression
|
the difference between the freezing points of the pure solvent and a solution of a nonelectrolyte in that solvent

|
hydronium ion
|
H3O+
|
|
ionization
|
ions are formed from solute molecules by the action of the solvent
|
|
molal boiling-point constant
|
the boiling-point elevation of the solvent in a 1-molal solution of a nonvolatile, nonelectrolyte solute
|
|
molal freezing-point constant
|
the freezing-point depression of the solvent in a 1-molal solution of a nonvolatile, nonelectrolyte solute
|
|
net ionic equation
|
An equation that includes only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution
|
|
nonvolatile substance
|
a substance that has little tendency to become a gas under existing conditions
|
|
osmosis
|
The movement of solvent through a semipermeable membrane from the side of lower solute concentration to the side of higher solute concentration
|
|
osmotic pressure
|
the pressure required to stop the process of osmosis
|
|
semipermeable membrane
|
a barrier that allows some substances to pass through while preventing the movement of others
|
|
spectator ions
|
ions that do not undergo a chemical change when a reaction occurs in an aqueous solution
|
|
strong electrolyte
|
a compound of which all or almost all of the dissolved compound exists as ions in an aqueous solution
|
|
weak electrolyte
|
a compound of which a relatively small amount of the dissolved compound exists as ions in an aqueous solution
