Increase in osmotic pressure
Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in its pure solvent by osmosis. Potential osmotic pressure is the maximum osmotic … See more Jacobus van 't Hoff found a quantitative relationship between osmotic pressure and solute concentration, expressed in the following equation: $${\displaystyle \Pi =icRT}$$ where See more Consider the system at the point when it has reached equilibrium. The condition for this is that the chemical potential of the solvent (since only it is free to flow toward equilibrium) on both … See more • What is Osmosis? Explanation and Understanding of a Physical Phenomenon See more Osmotic pressure measurement may be used for the determination of molecular weights. Osmotic pressure is an important factor affecting biological cells.
