Osmosis/Diffusion Practice Problems




This cell containing an aqueous solution enclosed in a selectively permeable membrane has just been immersed in this box containing a different solution. The membrane is permeable to water and glucose, but not to the sucrose.



The beaker below has a solution of protein on either side of a selectively permeable membrane. The membrane is permeable to water but not to the protein.


What if instead of the protein you put 1,000 molecules of NaCl in side A of the beaker and 1,000 molecules of glucose in side B of the beaker as seen below. The membrane is permeable to water, but not to the NaCl or the glucose.
