Osmotic potential can be understood as the ability of a solution to undergo osmotic pressure and prevent osmosis.

  • When solutes are added to the pure water, its free energy is reduced as the number of free water molecules has reduced.
  • It is the decrease in the chemical potential of pure water due to the presence of solute particles in it.
  • It is the pressure with which a solution can attract the solvent molecules towards itself.
  • Hence, every solution that has some solute has the osmotic potential. 
  • It is equal to the osmotic pressure.
  • It is a negative force.

 

It is equal to the osmotic pressure. It is a negative force. Hence, the correct answer is option b.
