Presented below is an image of a semipermeable sac, containing 4% NaCl, 9% glucose, and 10% albumin, suspended in a solution with the following composition: 10% NaCl, 10% glucose, and 40% albumin. Assume the sac is permeable to all substances except albumin. Using the key choices, insert the letter indicating the correct event in the answer blanks. Key Choices: A. Moves into the sac B. Moves out of the sac C. Does not move Solution contains: NaCl: 10% Glucose: 10% Albumin: 40% Sac contains: NaCl: 4% Glucose: 9% Albumin: 10%

A sac made from dialysis tubing contains a solution of 4% NaCl and 16% glucose. It is suspended in a beaker containing a solution with the following composition: 10% NaCl, 16% glucose, and 40% albumin (a protein found in blood plasma). Assume that the sac is permeable to all substances except the albumin. (4 marks) Hint: Draw a diagram so you can picture how this is set up, then think about the difference between the concentrations. Select the best answer from the choices, A-D, to predict the net movement of NaCl, glucose, albumin, and water. A. Move out of the sac. B. Remain outside of the sac. C. Move into the sac. D. Remain in the sac.

00:01 Hello students, in this question it is being said that we have a semi -permeable which contains different solutes with their concentration is given which are the albumin in the sac is 10 % sodium chloride the sac is 4 % and glucose in the semi -permeable sac is 9 % and we have a solution with the same components but with different concentrations which are albumin with 40 % sodium chloride with 10 % and glucose with 10 % and it is also mentioned in the question that the semi -permeable sac is permeable to all the substances except albumin so albumin cannot pass this semi -permeable sac.
01:35 Now we are being asked using the key choices which are given below insert the letter indicating the correct event in the in your answer the answer choices are we have to tell which one which component moves in or out of the sac or which do not move in or out of the sac.
01:57 So suppose this is a sac which is inside a container having a solution with the respective concentration and the respective concentrations of the same components in the sac.
02:12 Now let's talk about this sodium chloride as we know that sodium chloride is 4 % inside the sac while it is 10 % outside the sac which means that the sodium chloride move inside of the sac because its concentration is high outside and low inside and since the semi -permeable membrane allows sodium chloride to pass through the semi -permeable membrane so it will enter from solution into the sac so the sodium chloride will move into the sac.
03:04 Now coming to the glucose here glucose is 9 % inside the sac while it is 10 % outside the sac so its concentration is higher outside than inside and it can pass the semi -permeable membrane so it will move into the semi -permeable sac also glucose will move into the sac...
