Question

The water potential of pure water is:

• A. Zero
• B. Less than zero
• C. More than zero but less than one
• D. More than one

Answer 1

The correct option is A Zero

Water potential is the difference in chemical potential of water in a system over its pure state at the same temperature and pressure.

The water potential of pure water is zero and that of the solution will be a negative value.

Water potential is represented by the sign Ψw.
