Osmotic Pressure


  • Osmotic pressure depends on the amount of solute that is present in the solvent (such as water).
  • It also depends on the temperature of the solution.
  • The movement of water from an area of low concentration of solute to an area of higher concentration of solute.
  • The movement of water molecules through a selectively permeable from a region of high water concentration to low water concentration is called osmosis.
  • The pressure that needs to be applied to a solution to stop the movement of a solvent into it, when the solution and solvent (such as the water) are separated by a semipermeable membrane that only allows the solvents to pass through.
  • Osmotic pressure can prevent osmosis, which is the movement of a solvent (such as water) through a semipermeable membrane from a solution that has a lower concentration of solutes to one that has a higher concentration of solutes.
