DEMONSTRATING OSMOSIS USING NON-LIVING MATERIAL
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).
