| Statement A: Pure water has maximum water Potential |
| Statement B: The osmotic potential is zero in pure water. |
A) Both statements are correct and B is not the reason for A.
B) Both statements are incorrect.
C) Both statements are correct and B is the reason for A.
D) Both statements are correct.
Correct Answer: C
Solution :
: Water potential is the potential energy of water relative to pure water in reference conditions. Pure water has maximum water potential, whereas, addition of solutes to water lowers the water potential. Osmosis is a special type of diffusion in which water is diffuses from its pure state i.e., higher water potential to concentrated solution i.e., lower chemical potential through a semipermeable membrane. Since pure water has no difference in chemical potential, it has zero osmotic potential.
