Solute potential of pure water and its solution are:
Options
- A0 and 1
- B0 and 0
- C0 and more than 0
- D0 and less than 0
Correct answer
D. 0 and less than 0
Step-by-step solution
By definition," Water potential is the potential energy of water per unit volume relative to pure water in reference conditions." Thus, water will move from a higher water potential region to the lower potential region through the semipermeable membrane. It can be summarized as total of pressure potential, gravity potential and solute potential. Water potential of a fluid is reduced due to presence of solute as water molecules cluster around solute particles and this is referred to as solute potential. Pure water h
