Diffusion and Osmosis

…

…would possibly decrease or remain the same. 6. In order to remove the salt from the protein solution, a diffusion and dialysis system would be set up in which the cut off value in molecular weight of the semipermeable membrane is less than 65,000 but large enough to allow the substance with the smaller molecular weight in the mixture to diffuse out of the membrane. This way the salt could, through dialysis, be separated from the mixture.
