ICSE Class 10 Answered
does osmotic pressure occur due to the weight and pressure exerted by the liquid in the cell?

Expert Answer
- Osmotic pressure is the pressure developed by diffusion of a liquid or solvent through a membrane.
- The solvent passes from the dilute to the more concentrated solution through the membrane separating the two solutions.
- The presence of dissolved material in a solvent lowers the escaping tendency of the solvent molecules; the greater the concentration, the more the escaping tendency is lowered.
- Accordingly, the solvent will diffuse or pass through a membrane to a region of greater concentration, thus diluting the concentration of the solution.
- Osmotic pressure does vary depending on the pressure exerted by the solvent on the membrane and the volume of the solvent.
