Purpose: To determine permeability of a dialysis membrabe through the observation of

different dyes' ability to penetrate it.

Hypothesis: Because molecules having molecular weights greater than 10,000 cannot penetrate

the dialysis membrane, the orange dye, having molecular weight of 300, will penetrate the

membrane while the violet dye, having a molecular weight of 100,000, will not and will continue

Experimental Design: First, two beakers were filled with distilled water. Then, in both beakers

pieces of dialysis tubing were placed; one filled with violet dye and distilled water and the other

with both orange and violet dye. The dialysis tubings were then checked within 30 minutes from

when they were filled with the dyes and again within 24 hours.

Procudure: First, a knot was tied at one end of each piece of dialysis tubing starting

approximately one inch from the end. The tubings were kept moist in order to facilitate filling

them with the dyes, but were careful to not have to much water inside of them. Then, two

beakers were filled with 250ml of distill

3. a. Yes, changing the water bath would alter the Keq because the molecular concentration
