Question

Define osmotic pressure.​

Answer 1

Answer:

the pressure that would have to be applied to a pure solvent to prevent it from passing into a given solution by osmosis, often used to express the concentration of the solution.

Answer 2

Definition

Osmotic pressure is defined as the pressure that must be applied to the solution side to stop fluid movement when a semipermeable membrane separates a solution from pure water. From: Quantitative Human Physiology, 2012.

Example

An excellent example of a semipermeable membrane is that inside the shell of an egg. After shell removal is accomplished with acetic acid, the membrane around the egg can be used to demonstrate osmosis. Karo syrup is essentially pure sugar, with very little water in it, so its osmotic pressure is very low.
