Question

The osmotic pressure of a solution increases as

Answer 1

The osmotic pressure of a solution is a colligative property, which means that it depends on the number of particles of solute in the solution.

Formula: Osmotic pressure = MRT, where M is the molarity of the solution, R is the universal constant of ideal gases and T is the absolute temperature of the solution.

So, the answer is the option .: the osmotic pressure of a solution increases as the number of particles of solute in the solution increases.

Answer 2

The answer is option C  Explanation: Basically more solute particles will require the solvent to rush in through the semipermeable membrane to fix the high concentration creating a difference in volume between two sides of that membrane. And to even out the volumes on both sides, more (osmosis) pressure will be needed to push down on the solution with higher volume.   Anyways, its too confusing to explain, the answer is C and that’s all that matters.
