Define hypertonic, hypotonic and isotonic solutions. State the movement of water in these solutions.

  • A hypertonic solution is a solution that has more solutes and it had higher osmotic pressure than other solutions.
  • A hypotonic solution is a solution that has fewer solutes and it had lower osmotic pressure than other solutions.
  • An isotonic solution refers to a solution that has the same amount of solutes and therefore, the same osmotic pressure with another solution.
  • Water tends to diffuse from hypotonic solution to hypertonic solutions and shows no net osmotic pressure movement from one isotonic to another isotonic solution.
