The value of water potential for pure water is
Options
(a) always positive or more than zero
(b) always negative or less than zero
(c) always zero
(d) variable in different solution
Correct Answer:
always zero
Explanation:
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 of 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, the water potential of a solution is always less than zero.
