The solution in the arms of a u-tube are separated at the bottom of the tube by a selectively permeable membrane. the membrane is permeable to sodium chloride but not to glucose.
side a is filled with a solution of 0.4 mols of glucose and 0.5 mols of sodium chloride (nacl), and side b is filled with the a solution containing 0.8 mols of glucose and 0.4 mols of sodium chloride. initially, the volume in both arms is the same.
a. initially at the sun of the experiment, which of the following is true?
a. side a is hypertonic to side b
b. side a is hypotonic to side b
c. side a is hypertonic to side b with respect to glucose
d. side a is hypotonic to side b with respect to nacl
b. after diffusion and equilibrium:
how many mols of glucose are on side a? side b?
how many mols of nacl are on side a? side b?
c. if you examine side a after three days you should find
a. a decrease in the number of mols of nacl and glucose and an increase in the water level
b. a decrease in the number of mols of nacl and a decrease in the water level
c. a decrease in the number of mols of nacl, an increase in water level, and no change in the number of mols of glucose
