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
- A22.4 atm
- B2.2 atm
- C-2.24 bars
- 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.
