A measure of the amount of solute in a given amount of solvent of solution
number of moles/liters of solution
v1m1=v2m2 only with water
moles of solute/kg of solvent
mass of solute/mass of solutionX100
The separation of ions that occur when an ionic compound dissolves
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.
ions that do not take part in a chemical reaction and are found in solution both before and after the reaction
the process whereby solute molecules became ions by the action of the solvent
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
boiling point elevation
