Consider the following statements regarding water potential:
I. Water potential is the potential energy of water relative to pure free water (e.g., deionized water)
in reference conditions.
II. Typically, pure water at standard temperature and pressure (or other suitable reference condition) is defined as having a water potential of 0.
III. The addition of solutes to water increases its potential (makes it more negative), just as the increase in pressure lowers its potential (makes it more positive).
The correct statements are:
1. I, II and III | 2. I and II |
3. I and III | 4. II and III |
