concentration
A measure of the amount of solute in a given amount of solvent of solution
molarity
number of moles/liters of solution
dilution formula
v1m1=v2m2 only with water
molality
moles of solute/kg of solvent
mass percent
mass of solute/mass of solutionX100
dissociation
The separation of ions that occur when an ionic compound dissolves
precipitate/precipitation
A solid produced as a result of a chemical reaction in solution
when precipitation occurs
precipitation occurs when the attraction between ions is greater than the attraction between ions and surrounding water molecules.
net ionic equation
includes only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution.
spectator ions
ions that do not take part in a chemical reaction and are found in solution both before and after the reaction
ionization
the process whereby solute molecules became ions by the action of the solvent
colligative properties
properties that depend on the concentration of solute particles but not the identity. ex: vapor pressure lowering, boiling point lowering, freezing point depression
freezing point depression
delta^ts=ksm. k=-1.86
boiling point elevation
delta^tb=kbm. k=.51
