Question

set up an experiment to demonstrate osmosis

Answer 1

Two some raisins in a bowl full of water..
After some hours you will observe that the raising are swelled up..
Now,
Put those swelled up raisins in a bowl full of water.. And some salt in it..
Here, you will observe the raisins will shrink..
Hope it helps..

Answer 2

An experiment to demonstrate osmosis:

• In this experiment we will take a deshelled eggs, 3 glasses, sugar, salt and pure water.

• Take the glasses and pour water in it.
• In one glass dissolve sugar and steer it well.
• In another glass take salt and steer it well.  
• Therefore we have one glass of pure water, one glass of sugar solution and one glass of salt solution.
• Now put eggs inside the glasses one by one.
• Wait for 6-7 hours for the process to take place.
• We can see that there is no change in the egg kept in the pure water.
• The egg kept in sugar solution shrinks and the egg kept in salt solution gets larger.

EXPLANATION:

The osmosis process led to the movement of water from high concentration to low concentration of solvent. It is done through a semi permeable membrane.
