Question

a student carried out an experiment to determine how different concentrations of sucrose solution will affect osmosis. the student set up dialysis of different sucrose concentrations. then the student massed the bags, placed them in beakers of distilled water for thirty minutes, and then removed the bags. the masses were taken again and the percent change for each bag was calculated. the results were graphed and are shown here. which statements best summarize the experimental data. choose all that apply. a low sucrose concentrations caused more water to move out of the bags. b high sucrose concentrations caused more water to move out of the bags. c low sucrose concentrations caused more distilled water to move into the bags. d high sucrose concentrations caused more distilled water to move into the bags. e there is a correlation between sucrose concentration in the bag and the rate of osmosis in the bag.

Explanation:

Osmosis is the movement of water across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this experiment, distilled water is outside the bags and sucrose solutions are inside. As the percent change in mass increases with increasing sucrose concentration, more water is moving into the bags with higher sucrose concentrations. Also, the linear relationship in the graph shows a correlation between sucrose concentration and the rate of osmosis.

Answer:

D. High sucrose concentrations caused more distilled water to move into the bags.
E. There is a correlation between sucrose concentration in the bag and the rate of osmosis in the bag.
