9401.	Question : The water potential of pure water changes when solute is added to it.
Answer» Solution :The water POTENTIAL of pure water goes to its negative value when solute is added to it. Pure water has the maximum water potential. Water molecules will always move from pure water into any solution on the other side of a partially permeable MEMBRANE. The maximum water potential is zero. All solutions have a LOWER water potential than pure water, because the concentration of water molecules in the solution is lower than that in pure water Thus y always has a negative value and any DILUTION of water with a solute ESTABLISHES a potential that is less than that of pure water.
