Question

what do you mean by the presence so called osmotic ???

Answer 1

⭐Osmotic pressure is the force which is caused by a solution that is passing through a semi permeable surface by the process called osmosis,

➡which is equal to the force required to resist the solution from passing back through the surface.

✨Its example is the process to filter water.

✨A semipermeable membrane is that inside the shell of an egg.

⭐Formula :——
M is the molar concentration of dissolved species (units of mol/L). R is the ideal gas constant (0.08206 L atm mol-1 K-1).

⭐Osmotic pressure on a cell is created when the cells has greater solute concentration than the concentraton in environment.

⭐Osmotic pressure the pressure of a water solution of salts exerted in either direction against a semipermeable membrane.

Answer 2

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.[1] 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.

Osmosis occurs when two solutions, containing different concentration of solute, are separated by a selectively permeable membrane. Solvent molecules pass preferentially through the membrane from the low-concentration solution to the solution with higher solute concentration. The transfer of solvent molecules will continue until equilibrium is attained.[1][2]
