If any solute is added in pure water, what will be the effect on the value of water potential?

Options

  1. AValue of water potential is increased.
  2. BValue of water potential is decreased.
  3. CThere is no change in its value.
  4. DValue of water potential becomes more than D.P.D.

Correct answer

B. Value of water potential is decreased.

Step-by-step solution

Pure water has the maximum water potential, which is zero at standard temperature and pressure. When a solute is added to pure water, the concentration of free water molecules decreases, which lowers the free energy of water. This results in a decrease in the water potential, making it negative. Therefore, the value of water potential is decreased. Answer: Value of water potential is decreased.
