Which one of the following statements is wrong?

Step-by-step solution

Water potential is the difference in the free energy or chemical potential per unit molal volume of water in a system and that of pure water at the same temperature and pressure. It is represented by greek letter Ψ (psi) or more accurately Ψ w Water potential or Ψ w is the sum total of Ψ s a n d Ψ p . Ψ w = Ψ s + Ψ p where Ψ s → solute potential Ψ p → pressure potential
