Which of the following statements is wrong?
Water potential is the difference in free energy or chemical potential per unit molar volume of water in a system and that of pure water at the same temperature and pressure.
It is represented by the Greek letter Ψ (psi) or more accurately Ψ w.
Water potential or Ψ w is sum of total Ψ s + Ψ p
Ψ w = Ψ s + Ψ p
Where Ψ s → solute potential
Ψ p → pressure potential
