Solute Potential is the amount where

(1) Dissolution of a solute causes lowering of water potential

(2) Increase of solute causes increase of water potential

(3) Increase of solute causes decrease in osmotic pressure

(4) Increase of solute causes increase in solute potential

Find the correct one.

(1) All the solutes have lower water potential than pure water given that solution is under external pressure

(2) All the solutions have lower water potential than the pure water

(3) All the solutions have higher water potential than the pure water

(4) All the solutions have lower water potential than pure water unless solution is under such external pressure which is more than the solute potential
