Which of the following has maximum water potential?

Question

Which of the following has maximum water potential? (A) Pure water (B) 2 % sucrose solution (C) 4 % glucose solution (D) 10 % sodium chloride solution

Tardigrade Admin · Accepted Answer

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 addition of solutes.
