Key Topics to Revise

1

Components and Types of Solutions

  • Solution = homogeneous mixture of solute + solvent
  • Solvent: component in same physical state as solution (usually in larger quantity)
  • Solute: substance dissolved in solvent (usually in smaller quantity)
2

Concentration Units

  • Multiple ways to express concentration: molarity, molality, normality, mole fraction, mass percentage
  • Molarity depends on temperature (volume changes)
  • Molality is temperature independent (mass doesn't change)
3

Henry's Law and Gas Solubility

  • Henry's Law: solubility of gas ∝ partial pressure
  • Applies only under specific conditions
  • Gas solubility decreases with temperature increase
4

Raoult's Law and Vapor Pressure

  • Partial vapor pressure ∝ mole fraction
  • Applies to ideal solutions
  • Total vapor pressure = sum of partial pressures
