  • A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.
  • Examples of Heterogeneous mixture are -  sand, oil, and water, etc.
  • In all the above examples, the soil is the heterogeneous mixture, as it contains several things mixed in a random ratio.
  • All soil is made up of inorganic mineral particles, organic matter (including living things), air, and water.
  • But all these qualities vary in uneven ratio every time.

  • A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. 
  • Examples of Homogeneous mixture are - Blood, milk, brass, steel, Vinegar, Wine, etc.
