Properties of solutions

Relationship between lattice energy and solubility

As lattice energy increases solubility decreases
Effect of temperature on the solubility of gasses and ionic solids

As temperature increases the solubility of gasses decreases while the solubility of ionic solids increases
Henry's Law

As the partial pressure of a gas over a solution increases the solubility of that gas increases

S=KhP
Molarity

Molarity (M)

M=moles of solute/L of solution
Molality

Molality (m)

m=moles of solute/Kg of solvent
Mass Percent

Mass % = mass of solute/mass of solution
Mole Fraction (X)

X_A= Moles of A/Total moles of solution
Raoult's Law

The vapor pressure of A is the product of the mole fraction of A times the vapor pressure of pure A

P_A = P_A⁰X_A
Vapor pressure in a solution with a non-volatile electrolyte

The vapor pressure is the product of the pure solvent times the mole fraction of the non-volatile solute

P_A = P_A⁰X_B
Vapor pressure when solute and solvent have similar intramolecular forces, that is they are miscible

Ptot = P_A⁰X_A + P_B⁰X_B
