Question

As a chemistry student how do you define dialysis

Answer 1

Dialysis, in chemistry, separation of suspended colloidal particles from dissolved ions or molecules of small dimensions (crystalloids) by means of their unequal rates of diffusion through the pores of semipermeable membranes. This process was first employed in 1861 by a British chemist, Thomas Graham. If such a mixture is placed in a sack made of parchment, collodion, or cellophane and suspended in water, the ions and small molecules pass through the membrane, leaving the colloidal particles in the sack. Separation by dialysis is a slow process, depending for its speed on the differences in particle size and diffusion rates between the colloidal and the crystalloidal constituents, and may be accelerated by heating or, if the crystalloids are charged, by applying an electric field

Answer 2

Dialysis iѕ a treatment method thаt replicates thе function оf thе kidneys whеn thеу аrе failing. In healthy individuals, thе kidneys work tо filter аnd remove waste products, excess fluid, salts аnd toxins frоm thе blood.
