Key Topics to Revise

1

1. Definition and Basic Concepts of Solutions

  • A solution is a homogeneous mixture of two or more substances with uniform composition and properties throughout
  • Solutions have only one visible phase (appear uniform to the naked eye)
  • Solute: The substance dissolved (present in lesser amount)
2

2. Types of Solutions

  • Solutions are classified based on: (a) physical states of solute and solvent, (b) type of solvent used, (c) amount of solute dissolved
  • Solid solutions: Both solute and solvent are solids (e.g., alloys like copper in gold)
  • Liquid solutions: Solvent is liquid (most common type)
3

3. Solubility and Factors Affecting It

  • Solubility: The maximum amount of solute that dissolves in 100 g of solvent at a given temperature to form a saturated solution
  • Solubility is expressed in grams per 100 grams of solvent (g/100g solvent)
  • Solubility depends on three main factors: nature of solute and solvent, temperature, and pressure
4

4. Concentration of Solutions

  • Concentration: The amount of solute present in a given amount of solution or solvent
  • Concentration can be expressed qualitatively (dilute vs concentrated) or quantitatively
  • Qualitative terms are subjective - same solution could be 'concentrated' or 'dilute' depending on comparison
