The osmotic pressure of a solution can be increased by :
The osmotic pressure of a solution can be increased by :
The correct option is A Increasing the number of solutes
The correct option A.
Explanation of the correct option:
Option A:
- Osmotic pressure, also known as osmosis pressure, is the lowest pressure that inhibits the inward flow of a pure solvent into a solution that is separated from it by a semipermeable membrane.
- The quantity of solute particles affects osmotic pressure. It varies in proportion to the solution's molarity.
- Osmotic pressure has a collaborative quality. In other words, rather than the density of the solute, it depends on its molar concentration. Simply put, the pressure needed to prohibit osmosis is the pressure used in a solution to stop water from permeating inward through a semipermeable barrier.
Explanation of the incorrect options:
Option B:
The osmotic pressure of a solution does not depend on the volume of the vessel. Hence, increasing the volume will not have any effect on the osmotic pressure.
Option C:
The osmotic pressure of a solution will not be increased upon removing the semipermeable membrane.
Option D:
The temperature rises in direct proportion to how quickly water molecules pass through the semipermeable barrier. Therefore decreasing the temperature will not increase the osmotic pressure.
Final answer: The osmotic pressure of a solution can be increased by increasing the number of solutes.
