Topics in Solutions

Types of Solutions and Basic Concepts

Solution = Solute + Solvent (homogeneous mixture with uniform properties throughout)
Solvent: Component present in largest quantity, determines physical state of solution
Solute: Component(s) present in smaller quantities

Concentration Units and Calculations

Six major concentration units: Mass %, Volume %, Mass/Volume %, ppm, Mole fraction, Molality
Mass percentage most common for solid-liquid solutions
Volume percentage used for liquid-liquid solutions

Solubility and Henry's Law

Solubility depends on nature of solute-solvent, temperature, and pressure
For solids in liquids: Generally increases with temperature (endothermic dissolution)
Pressure has negligible effect on solid-liquid solubility

Raoult's Law and Vapor Pressure

Vapor pressure of solution < vapor pressure of pure solvent (for non-volatile solute)
Raoult's Law: Partial vapor pressure ∝ mole fraction
For volatile liquid solutions: p_total = p₁⁰x₁ + p₂⁰x₂

Key Concepts

Solutions are classified based on physicalMass % = (mass of component/totalAt constant temperatureFor volatile liquidsIdeal solutions obey Raoult's law completely
