(N/A) $1$. Pure water has the highest water potential,which is defined as zero at standard temperature and pressure.
$2$. When a solute is dissolved in pure water,the concentration of free water molecules decreases.
$3$. This reduction in the concentration of free water molecules leads to a decrease in the water potential of the solution.
$4$. Therefore,all solutions have a lower water potential than pure water.
$5$. The magnitude of this lowering due to the addition of solute is known as solute potential $(\Psi_{S})$,which is always negative.
