Question

Pure water will jave the greatest water potential.Water potential of pure water at standard temperatures, which is not under any pressure, is taken to be zero. Please explain me why??? ​

Answer 1

Answer:

hey here's the answer

Explanation:

Water at standard temperatures, which is not under any pressure is taken to be zero because if some solute is mixed up with pure water then the solution has less free water molecules n the concentration of pure water decreases reducing water potential....

Hope it helped uuu....

Answer 2

$\large\sf\pink{\longrightarrow Answer:}$

The water potential of pure water in an open container is zero because there is no solute and the pressure in the container is zero. Adding solute lowers the water potential

water potentialis the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis , gravity, mechanical pressure, or matrix effects such as surface tension. Water potential has proved especially useful in understanding water movement within plants, animals, and soil. Water potential is typically expressed in potential energy per unit volume and very often is represented by the Greek letter Ψ.

Water potential is always negative, water being pure has a potential of zero as it can diffuse the easiest. The higher the concentration the more negative the water potential.
