How you can demonstrate the phenomenon of osmosis in the laboratory?
1. Remove the outer skin of the potato and cut the one end flat.
2. Scoop out a cavity from the other end of the potato running almost upto the bottom.
3. Fill one tuber with concentrated solution of sugar and water in the other.
4. Mark the level of the sugar solution and water with the help of pins.
5. Place the potato containing sugar solution in a beaker containing water, and the potato containing water in the beaker containing sugar solution.
The level of the sugar solution in the first potato increases because the water moves from the beaker into the cavity through the semipermeable membrane of potato.
The level of the water in the potato containing water decreases because the water moves from the cavity into the beaker through the semipermeable membrane.
