The osmotic pressure of 1 M solution of sucrose is 22.4 atm. What will be the osmotic potential& of 0.1 M sucrose solution?

Options

  1. A22.4 atm
  2. B2.2 atm
  3. C-2.24 bars
  4. D0

Correct answer

C. -2.24 bars

Step-by-step solution

Osmotic potential is a modern term for osmotic pressure. The osmotic pressure for a solution is positive, but its value is negative for osmotic potential.

Hence, Osmotic pressure = - Osmotic potential.

The osmotic pressure of 1M solution is 22.4 atm, hence for a 0.1M solution it will be 2.24 atm.
