Why is cellophane membrane semi-permeable, even though urea, uric acid and creatinine can diffuse in dialysis?
Answers
Explanation:
the cell membrane is the biological membrane that separates the interior of a old cells from the outside environment which protects is helped from the environment the cells membrane consists of a liquid
Answer:
Dialysis is the separation of colloids from dissolved ions or molecules of small dimensions, or crystalloid, in a solution. A colloid is any substance that is made of particles that are of an extremely small size: larger than atoms but generally have the size of 10-7 cm ranging to 10-3 cm. A crystalloid is a substance that has some or all of the properties of a crystal or a substance that forms a true solution and diffuses through a membrane by dialysis. Dialysis is a process that is like osmosis. Osmosis is the process in which there is a diffusion of a solvent through a semipermeable membrane.
Explanation:
Introduction
In 1861, chemist Thomas Graham (how developed Graham's Law) used the process of dialysis, a process used to separate colloidal particles from dissolved ions or molecules. Dialysis is possible because of the unequal rates of diffusion through a semipermeable membrane. A semipermeable membrane is a membrane that lets some molecules to pass through it while not letting others. Examples of semipermeable membranes include parchment and cellophane.
