We are going to be checking on a practical which will be an alternative to practical...
AIM :- **TO DEMONSTRATE OSMOSIS USING NON LIVING MATERIAL.
METHOD :- A piece of cellophane of cigarette packet is tied over to the mouth of a thistle funnel carefully and tightly. The cup of the thistle funnel is filled with sugar solution while the beaker contains water.
The cuo side carrying the semi-permeable membrane (cellophane) is immersed into the beaker of water, the experiment is left fir one day. The control experiment is similarly arranged but instead of filling the funnel with sugar solution it is filled with water.
RESULT :- After a few hours the leve of liquid in the funnel has risen from its original mark. There is no rise in the control experiment.
CONCLUSION :- Water has passed through the semi-permeable membrane (cellophane) to the sugar solution by osmosis (endosmosis).
