Question

define osmotic pressure. write the mathematical expressions for osmotic pressure & concentration of solution & explain the terms involved​

Answer 1

Explanation:

Osmotic Pressure is the minimum pressurewhich needs to be applied to a solution to prevent the inward flow of its pure solventacross a semipermeable membrane.It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis. Potential osmotic pressure is the maximum osmotic pressure that could develop in a solution if it were separated from its pure solvent by a semipermeable membrane.

Osmotic pressure symbol= π

π∝C [Molarity]

π∝T

∴π=STC where S= solution constant

∵ Molarity= (V) Volume in litresMoles and moles= Molar mass(m)weight(W)

∴π=mW×V1×S.T⟶ From this equation molar mass can be determined.

Osmotic Pressure.....✒

• It 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 pure solvent by osmosis.
• Potential osmotic pressure is the maximum osmotic pressure that could develop in a solution if it were separated from its pure solvent by a semipermeable membrane.
