Molarity |
M=moles solute/liters solution |
|
|
McVc=MdVd |
M=molarity V=volume liters c=concentrated d=dilute |
|
|
mole fraction |
Xa= moles(a)/total moles =na/ntotal where Xa + Xb+...=1 |
|
|
3 principles of solubility |
interactions between the solute and solvent particles temperature at which solution is formed pressure of a gaseous solute |
|
|
correlation between molar mass and water solubility |
solubility decreases as molar mass increases |
|
|
effect of temperature on solubility |
an increase in temperature always shifts the position of an equilibrium to favor an endothermic process |
|
|
Solution absorbing heat vs releasing heat |
increase in temp increases solubility if solution is endothermic, increase in temp decreases solubility if solution is exothermic |
|
|
effect of pressure on solubility |
raising pressure increases solubility |
|
|
Cg=KPg |
Cg = concentration of the gas Pg= partial pressure of the gas k=some constant |
|
|
colligative properties |
properties that depend primarily on the concentration of solute particles rather than their nature vapor pressure lowering, osmotic pressure, boiling point elevation, freezing point depression |
