Solution

All of these are applications of Dialysis.

  1. Concentration of macromolecules: Dialysis can be used to concentrate macromolecules. This is done by placing the solution of macromolecules in a dialysis bag and immersing it in a solvent. The small molecules will diffuse out of the bag, leaving the macromolecules concentrated inside.

  2. Removal of acids or alkali from products: Dialysis can also be used to remove unwanted small molecules such as acids or alkalis from a solution. This is done by placing the solution in a dialysis bag and immersing it in a buffer of the desired pH. The small molecules will diffuse out of the bag, leaving the product in the desired pH range.

  3. Purification of biotechnological products: Dialysis is often used in biotechnology to purify products. This is done by placing the product in a dialysis bag and immersing it in a solvent. The unwanted small molecules will diffuse out of the bag, leaving the purified product inside.
