• Solute

  The substance that is being dissolved using the solvent
• Substances that can be dissolved in water

  • Sugar
  • Salt
• Substances that cannot be dissolved in water

  • Milk
  • Nail polish
  • Paint
• Factors affecting solubility


  • Nature of solute and solvent
  • Temperature of solvent
  • Manner of stirring
  • Amount of solvent
  • Size of solute
• As temperature increases

  Solubility increases
• As temperature decreases

  Solubility decreases
• Dilute

  A solution with a small amount of solute
• Concentrated

  A solution with a lot of solute in the given solvent
• Solute dissolves faster by diffusion
• Solubility is the maximum amount of a solid substance that will dissolve in a given amount of solvent at a specific temperature
