OSMOSIS AND OSMOTIC PRESSURE

What is the effect of temperature on the osmotic pressure of solution?

• It decreases with increase in temperature

• It decreases very very slowly with increase in temperature

• No effect of temperature

• It increases with increase in temperature

The process of movement of solvent through a semipermeable membrane from the solution to the pure solvent by applying excess pressure on the solution side is called

• Reverse osmosis

• Diffusion

• Osmosis

• Association

Which one of the following processes is used for desalination of sea water ?

• Electrophoresis

• Diffusion

• Reverse osmosis

• Osmosis

The phenomenon of flow of solvent molecules through a semi permeable membrane from pure solvent to solution is called

• Association

• Osmosis

• Reverse osmosis

• Diffusion

Assertion

Lowering of vapour pressure is directly proportional to osmotic pressure of the solution.

Reason

Osmotic pressure is a colligative property

• Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

• Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

• Assertion is correct but Reason is incorrect

• Assertion is incorrect but Reason is correct
