Zero and zero

Vedclass · Answer

(A) By definition, the water potential $(\Psi_w)$ of pure water at standard temperature and pressure is defined as zero. Osmotic pressure is the pressure required to prevent the movement of water into a solution across a semi-permeable membrane. Since pure water contains no solutes, its osmotic pressure is zero. Therefore, both the water potential and the osmotic pressure of pure water are zero.
