Detailed Solution

The more the solute molecules in solution, the lower (more negative) is the solute potential of solution. If some solute is dissolved in pure water, the solution has fewer free water molecules and the concentration (free energy) of water decreases, reducing its water potential. For a solution at atmospheric pressure, water potential = solute potential
