Detailed explanation-1: -Hence, pure water has highest water potential. By convention water potential of pure water has been fixed as zero.
Detailed explanation-2: -The greatest amount of water potential that any volume of water has when standard atmospheric pressure is applied to that volume, which is defined as 0. This is referred to as the water potential of distilled water. As a result, distilled water has the greatest ability to move and hence displace other items.
Detailed explanation-3: -Pure water has the highest concentration of water molecules. Therefore, it has the highest water potential. When some solute is dissolved in water, the water potential of pure water decreases.
Detailed explanation-4: -The largest water potential any volume of water can have, if only standard atmospheric pressure is being applied to that volume of water, is defined as 0. This is the water potential for distilled water. Distilled water has the greatest potential to move, and thus displace another object.
