The pressure exerted by dissolved particles in a solution or colloid that pulls water across a semipermeable membrane is known as what?
Correct Answer
osmotic pressure
Explanation
Osmotic pressure is the pressure exerted by dissolved particles in a solution or colloid that pulls water across a semipermeable membrane. The higher the concentration of dissolved solutes, the greater the osmotic pressure, and the stronger the tendency for water to move in by osmosis to dilute the solution.
