soluble in each other in any proportion.
What is a rule of thumb for when a solute will dissolve in a solvent?
Like dissolves like.
Substances with similar intermolecular forces will dissolve in each other.
What are the six intermolecular forces in order of decreasing strength.
Ion Induced Dipole
Dipole Induced Dipole
of a solution(⌂H
Process of surrounding solute particles with solvent particles (solvent particles are water for hydration)
What affect does charge density have on the heat of hydration?
The higher the charge density, the more negative ⌂H
What is Henry's law?
The solubility of a gas (S
) is directly proportional to the partial pressure of the gas (P
) above the solution
This means that gases become less soluble in hotter solutions.
What is Raoult's law?
vapor pressure of a solvent (P
) above a solution equals the mole fraction of solvent (X
) times the vapor pressure of the pure solvent(P°
What physical properties depend on the number of solute particles, not their chemical identity?

Boiling point elevation
Equations for freezing point depression and boiling point elevation?
Find Osmotic pressure
What is the van't Hoff factor (i)?

for vapor pressure lowering
for boiling point elevation
