|
colligative properties |
properties depending on the concentration of a solution, but not the identity of the solute. directly proportional to the number of particles in a solution |
|
|
ionic solid |
made up of charged particles held together by ionic attraction |
|
|
molecular solid |
molecules held together through intermolecular forces |
|
|
dissociation |
separation of ions; occurs when an ionic compound dissolves |
|
|
ionization |
forming ions in water |
|
|
degree of ionization |
strong-ionizes completely or nearly completely weak-barely or does not ionize |
|
|
nonelectrolytes |
no ions |
|
|
vapor pressure lowering |
nonvolatile (non-electrolyte) substance is added, raising the boiling point and lowering the freezing point |
|
|
Freezing point depression |
change in freezing point |
|
|
boiling point elevation |
change in boiling point |
|
|
Osmotic Pressure |
pressure that is applied to a solvent to prevent it from going into another solution via osmosis |
|
|
concentrated electrolytic solution |
a solution that is so concentrated the ions do not stay separate, causing their to be less moles in the solution |
|
|
as more solute is dissolved into a solvent, the vapor pressure |
decreases |
|
|
good luck |
have a cat |
|
|
1 mol of KNO3 makes how many mols of ions? |
2 (1 K and 1 NO3) |
