Write the activity of diffusion , osmosis, endoosmosis and exoosmosis

Dear student,

Activity for diffusion-

Take water in a beaker. Add a few copper sulfate crystals at one place and leave it as it is for some time without disturbing it. After some time we can see that beaker contains a uniformly coloured solution. Here, both water and copper sulfate diffuse independently. With this experiment, we can infer that solutes move from a higher concentration to the lower concentration in a solution.

Activity for osmosis shown below-

Aim : To show the process of osmosis.

Materials required : Bowls , sugar , raisins , water 

Procedure : 
1) Both the beakers will be taken. Keep on adding sugar in water in the bowl 1 to make it concentrated solution . But in beaker 2 , add a small amount of sugar in the bowl 2 to make it a dilute solution.

2) The raisins are kept in both the bowls for few hours.

3) When you a pick a raisin from the bowl 1 , the raisin will be shrink as water has moved from inside to outside. The solution is more sugary outside than inside . 

4) The raisin of bowl 2 will get swelled up as water moves from outside to inside. 

 

Regards.
