Difference between Osmotic pressure and Osmotic potential
1. Osmotic pressure is the pressure which develops in an osmotic system due to entry of water into it. Osmotic potential is the lowering of free energy of water in a system due to the presence of solute particles.
2. Osmotic pressure develops only in a confined system. Osmotic potential is present whether the solution occurs in a confined system or an open system.
3. The value of osmotic pressure is positive though numerically equal to osmotic potential. The value of Osmotic potential is negative though it is numerically equal to osmotic pressure.
