Vedclass · Accepted Answer

Negative water potential

Vedclass · Answer

(A) The water potential of pure water at atmospheric pressure is defined as zero. When a solute is added to pure water,the concentration of free water molecules decreases,which reduces the kinetic energy of the water molecules. This reduction in free energy results in a decrease in water potential. Since the water potential of pure water is zero,any reduction leads to a negative value. Therefore,the addition of a solute to pure water causes a negative water potential.
