Diffusion lab semipermeable membrane help

  1. Oct 30, 2008 #1
    1. The problem statement, all variables and given/known data
    diffusion thru a semipermeable membrane.

    2. Relevant equations
    section 1 of the lab

    LAB - dialysis tubing containing distilled water and the beaker containing glucose and starch .. put it in water.
    Leave it over night and jot the changes, it goes through osmosis but i odnt know what actually happens to the dialysis and such because i wasn't there.
    section 2 of the lab

    TT1: contains water and benedict
    TT2: contains water and starch
    TT3: contains starch and benedict
    TT4: contains starch and iodine

    you put these on a hot plate and observe.. the colors will then change which i dont know what it changes to and i need to make a chart.

    3. The attempt at a solution
    no solution, I have been absent on the day of the lab and i have to make up for it, i have been looking all over the searches and i cant find the lab answers.

    any info will be alot of help. or reference sites, thank you

    found a similar lab to mine, but i still need help :)
