Write any one precaution you took while preparing semi-permeable
membrane using egg?
Answers
Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by diffusion—or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.[dubious – discuss] The rate of passage depends on the pressure, concentration, and temperature of the molecules or solutes on either side, as well as the permeability of the membrane to each solute. Depending on the membrane and the solute, permeability may depend on solute size, solubility, properties, or chemistry. How the membrane is constructed to be selective in its permeability will determine the rate and the permeability. Many natural and synthetic materials thicker than a membrane are also semipermeable. One example of this is the thin film on the inside of the egg. Note that a semipermeable membrane is not the same as a selectively permeable membrane. Semipermeable membrane describes a membrane that allows some particles to pass through (by size), whereas the selectively permeable membrane "chooses" what passes through (size is not a factor).
Answer:
Semi-permeable membrane may be defined as the membrane that allow the movement of some selected particles only. Cell membrane is the selectively permeable membrane.
The semi permeable membrane can be prepared by the use of egg. While preparing the membrane the exact chemical concentration must be used. Eggs must be soaked in dilute hydrogen chloride and the clean syringe must be used.
