Question

In the lab, students are soaking potato cores in different sucrose solutions overnight to observe the movement of water into and out of the potatoes. Observe the picture. Which result, below, best matches the picture? A) The potato in the distilled water doubled in mass due to the hypotonic solution. B) The potato in the 2M solution remained the same because it was an isotonic solution. C) The mass of the potato in the distilled water did not change because it was a hypotonic solution. D) The potato in the 8M solution decreased in mass because the solution was hypertonic to the potato.

Answer 1

Answer:

The potato in the 2M solution remained the same because it was an isotonic solution.

Answer 2

Answer:

There is no change in potato size which is placed in 2M sucrose solution.

Explanation:

When the potato is soaked into the sucrose solution osmosis will take place because potato acts as an semi permeable membrane. Osmosis is the process in which the solutes or ions or particles will get transferred from the region having higher concentration to the region having lower concentrations. But when the concentration is same no exchange of particles will takes place. That happened in 2M sucrose solution. So answer B is right. There is no change in potato size which is placed in 2M sucrose solution.
