Which among the following has highest water potential?
Options
(a) 1 m salt solution
(b) 1 m glucose solution
(c) distilled water
(d) 1 m iodide solution
Correct Answer:
distilled water
Explanation:
Distilled water has the highest water potential. The value of water potential is always negative or less than zero. Water potential of a solution is determined by using pure water as the standard or reference, which has zero water potential at normal temperature and pressure. The presence of solute particles reduces free energy of the water. Hence, it decreases the water potential in negative value. So, water potential of a solution is always less than zero.
