Question

why the water potential is always negative?

Answer 1

Hi friend,

The component of water potential that is due to the presence of solute molecules.

It always has a negative value as solutes lower the water potential of the system.

HOPE THIS HELPS YOU:-))

Answer 2

●Water pontential is negative when some solute is dissolved in pure water.

●So solution has fewer free water and the concemtration of water decreases reducing it's water potential.

●The magnitude of this lowering is due to dissolution of solute called solute potential which is always negative .

●more solute molecules liwer or more negative is potential.

●For solution at atmospheric pressure the water potential is equal to solute potential which is always negative.

●hence potential of water is negative.
