Question

Choose the correct answers from the alternatives given :
The osmotic pressure of pure water is

• A. 0
• B. 0.1
• C. 1
• D. 10

Answer 1

The correct option is A 0

Osmotic pressure is the minimum pressure applied to prevent the inward flow of solvent molecules from a dilute solution into the concentrated solution, where both solutions are separated by a semipermeable membrane.

The osmotic pressure would be zero if pure water were on both sides of the semi-permeable membrane.

So the correct answer is "0"
