(A) Raoult's law: For a volatile solute in solvent, partial pressure of solute $P_2=P_2^0x_2$ (IV) — ideal solution behavior for component 2.
(B) Henry's Law: For dilute gas in liquid, $p = K_H x$ (III) — solubility proportional to partial pressure (x is mole fraction of gas).
(C) Dalton's Law of partial pressure: For ideal solution of two volatiles, $P_{total}=P_1^0+(P_2^0−P_1^0)x_2$ (II) — total pressure as function of composition.
(D) Relative lowering of vapor pressure: $\frac{P_1^0 - P_1}{P_1^0} = x_2$ (I) — lowering due to non-volatile solute equals mole fraction of solute.
