A laboratory assistant prepared solutions of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose,
but forgot to label them. After realizing the error, the assistant randomly labeled the
flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D.
Design an experiment, based on the principles of diffusion and osmosis, that the
assistant could use to determine which of the flasks contains each of the four unknown
solutions.
Include in your answer
(a) a description of how you would set up and perform the experiment;
(b) the results you would expect from your experiment;
and
(c) an explanation of those results based on the principles involved.
(Be sure to clearly state the principles addressed in your discussion.)
WOULD THIS EXPERIMENT WORK
you could put a snall amount of each of the different solutions in dialysis tubes which are impermeable for sucrose. Then you place the filled tubes into the different solutions.
Lets say you put solution from flask A into a dialysis tube and then put this into flask B. If the tube swells it means it took up water from soulution B and that means that A has a higher osmolarity and therefore molarity of sucrose. This way you can test different solutions against each other and find out the order in which the osmolarity increases
