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

ψ (psi) denotes water potential. It is the potential energy of water per unit volume corresponding to pure water based on mentioned circumstances and are expressed in units of pressure. Water potential decreases with increases in solute concentration. Pure water has the highest water potential which is not under any pressure and at standard temperature is taken as zero. The osmotic potential ( Ψ π) of pure water is defined to be zero because there is no solute and the pressure in the container is zero. 

So, the correct answer is option C.
