When a concentrated solution is separated from distilled water by a semi permeable membrane, the concentrated solution will develop a force with which it draws water through the semi permeable membrane from the distilled water.
Osmotic pressure refers to the force with which a concentrated solution draws water to itself.
An osmometer is an instrument used to measure the osmotic pressure.
