WebOct 27, 2024 · Osmotic pressure (OP) or Solute potential (ψs): The pressure developed in a solution when it is separated from it’s pure solvent by means of semipermeable membrane is termed as osmotic pressure (OP). The OP of pure solvent is regarded as 0, so OP for solution is always positive. WebOsmotic potential of a solution: The osmotic potential of a solution can be measured with the help of an osmometer (Fig. 6-6). It is a simple apparatus consisting of a cylinder having water tight sliding piston and a differentially permeable membrane at one end. ultrasound tech near me
