Question

question 9 four potato slices of equal weight are placed in the following solutions: one in 1 m sugar solution one in 2 m sugar solution one in 5 m sugar solution one in pure water which of these potato slices is most likely to have gained weight after soaking for 5 minutes? a slice from the pure water solution b slice from the 1 m solution c slice from the 2 m solution d slice from the 5 m solution

Explanation:

Osmosis is the movement of water from an area of lower solute concentration to an area of higher solute concentration across a semi - permeable membrane. Potato cells have a certain solute concentration. Pure water has the lowest solute concentration among the given solutions. So, water will move into the potato slice in pure water, causing it to gain weight. In sugar solutions (1M, 2M, 5M), the solute concentration is higher than that inside the potato cells initially, and water will move out of the potato slices, causing them to lose weight.

Answer:

A. slice from the pure water solution
