Why does the level of solution rises from the initial level in the osmoscope?
Option: 1
Due to exosmosis of pure solvent across the potato
Option: 2
Due to loss of water from the potato
Option: 3
Due to endosmosis of pure solvent across the potato
Option: 4
Due to absorption of water by the potato
Answers (1)
- When the potato is peeled and the inner section of it is taken out with the help of a spoon or knife, it becomes U-shaped.
- It is then placed in a tray having a pure solvent.
- The cavity of the U-shaped potato osmoscope is filled with a 10% solution.
- A pin is marked at the initial level of the 10% solution in the potato osmoscope. This pin is labelled as an initial pin.
- After 2 hours, the level of the solution in the potato osmoscope will rise. This is endosmosis occurring due to the difference in the concentration of the solution.
- Hence, osmoscope is a device that describes the process of osmosis.
The level of the solution in the potato osmoscope rises due to the endosmosis occurring due to the difference in the concentration of the solution. Hence option c is correct.
