Question

You have a 5 mL sample of a protein in 0.5 M NaCl. You place the protein/salt sample inside dialysis tubing (see Fig.) and place the bag in a large beaker of distilled water. If your goal is to remove as much NaCl from the sample as possible, which would be more eff ective: (1) placing the dialysis bag in 4 L of distilled water for 12 h, or (2) placing the bag in 1 L of distilled water for 6 h and then in another 1 L of fresh distilled water for another 6 h?

(a) At start of dialysis
(b) At equilibrium
Section 2 Chemical Properties of Water
FIG. 2-14 Dialysis. (a) A concentrated solution
is separated from a large volume of solvent by a
dialysis membrane (shown here as a tube knotted
at both ends). Only small molecules can diffuse
through the pores in the membrane. (b) At
equilibrium, the concentrations of small
molecules are nearly the same on either side of
the membrane, whereas the macromolecules
remain inside the dialysis bag.
