Question

Place few potato cubes (raw) in sugar solution and leave it

undisturbed for few hours.(2 hrs)

a) What do you observe about the potato cubes?

b) Give reason for your observation.​
Please tell what is the reason

Answer 1

Answer:

Since a hypertonic solution has a high concentration of solvent, it causes the cells inside the potato to release water, allowing them to shrivel up and lose mass (Wootton and Campbell)

reason --

Through the process of Osmosis, water will move from a region of high water potential ('concentration') to low water potential. Therefore, water will slowly leave the cells of the potato and enter the sugar solution in an attempt to reach equilibrium and the potato will therefore lose mass.

Hope this helps

Answer 2

Answer:

Through the process of Osmosis, water will move from a region of high water potential ('concentration') to low water potential. Therefore, water will slowly leave the cells of the potato and enter the sugar solution in an attempt to reach equilibrium and the potato will therefore lose mass.

Explanation:

Cut potatoes into four groups of small, uniform cubes measuring 1/2 cm by 1/2 cm. Make four different solutions of sucrose: 10 percent, 5 percent, 1 percent and 0.01 percent. Weigh each group, on a mass balance, before immersing it in the appropriate sucrose solution for half an hour. After immersion, weigh each group again and have your students calculate the changes in the potato masses. Ask them to comment on why a group gained mass, lost mass or retained the same mass.
