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 wizard will be randomly labeled the flasks containing these four unknown solutions as a bottle, flask B, flask C, and D. Ball
Design an experiment based on the principles of diffusion and osmosis, that the assistant could use to determine what each vial with four unknown solutions.Include in a reply

May Snäll put a lot of each solution in different tubes for dialysis are impermeable to sucrose. Then placed in tubes filled with different solutions.
Assume that you are the solution in a bottle into a dialysis tube and then place this in vial B. If the tube is filled, meaning they took the water soulution B, which means that A has a higher osmolarity and thus the molarity of sucrose. In this way, different solutions with each other to try and find the order in which the increase in osmolarity.
I agree with Mel here.
However, you can enjoy a cocktail as they are just sugar water.
It would be the purpose of the question of the task in the distribution of defeat (not fool anyone here).
Now the task ..... Get four balls and fill them with the same amount of water. Place the ball in the solutions. Then, when .... 4 days or so balloons and eyes that are smaller than others. The smallest is the highest concentration of water is easily spread in the world where sugar and so osmosis occurs, is the balance to be sent.
Make sure that the answer now !!!!!!
After the determination by this method, you will find that their molar solutions now have too much water in them and the labels are wrong anyway concentration and do not really know the new concentrations. Your boss is very annoying, as one weeks time will be lost if the sugar is very cheap ... cheaper than the hourly rate. Then he went and he needs to find a new job .... all becauseYou disorderly and tried to hide the error, instead of reporting to his boss.
Personally, I would solutions. It would be less time.
