Which of the following has the maximum water potential?

Options

  1. APure water
  2. B2% sucrose solution
  3. C4% glucose solution
  4. D10% sodium chloride solution

Correct answer

A. Pure water

Step-by-step solution

Water potential is the difference in free energy or chemical potential per unit molal volume of water in a system and that of pure water at the same temperature and pressure. The water potential of pure water is zero and it decreases on the addition of solutes.
