Question

Choose the correct combination of labelling of the potato osmoscope experiment.

• A. a- final level, b- dotpin, c- initial level, d- sugar solution, e- potato tuber
• B. a- initial level, b- dotpin, c- final level, d- water, e- potato tuber
• C. a- final level, b- dotpin, c- initial level, d- water, e- potato tuber
• D. a- final level, b- dotpin, c- initial level, d- coconut oil, e- potato tuber
• E. a- initial level, b- dotpin, c- final level, d- coconut oil, e- potato tuber

Answer 1

The correct option is A a- final level, b- dotpin, c- initial level, d- sugar solution, e- potato tuber

In a potato osmoscope experiment, water moves into the osmoscope due to the process of endosmosis. This is because water is present in lesser amount in sugar solution and number of water molecules is more outside the potato osmoscope in the beaker. As water moves inside the potato osmoscope the level of water inside increases. To find out how much level increases, we can mark the initial level with the help of a pin and measure or note the level after some time gap.
