Q. 84.7( 3 Votes )

Water potential o A. 10

B. 20

C. Zero

D. None of the above

Answer :

The water potential of pure water at standard temperature is always zero.

Water potential (Ψw) is the sum of solute potential (Ψs) and pressure potential (Ψp): Ψw= Ψs+ Ψp. So when solute is dissolved in water, the water potential of pure water decreases or starts assuming a negative value.
