Question

Which of the following has higher water potential? (A) 1 M salt solution (B) 1 M sugar solution (C) Distilled water (D) 1 M sugar solution with 2-3 bars pressure applied to it

Pure water has highest water potential. NaCI is an electrolyte so number of ions increase in water and it leads to increase in osmotic pressure and hence decrease in water potential.
