Experiment for Demonstrating the Process of Osmosis
Object: To demonstrate the process of osmosis. Image Source : pacificwater.com.au Requirement: One big beaker or flask, one thistle funnel, strong cane sugar solution, pure water, semipermeable membrane (cellophane), one piece of gummed paper, wax, etc. Principle: “Osmosis is a process in which water or any other solvent flows through a semipermeable membrane from a lower concentrated solute solution to one of higher concentrated solute solution”. ADVERTISEMENTS: It is simply a case of diffusion, but the movement of solvent usually causes an obvious volume change, whereas the movement of solute has a negligible effect. Procedure: Take a thistle funnel and the piece of a semipermeable membrane is tied tightly across the button of the thistle funnel and the joint is waxed with melted wax to make it water-tight.Now fill up…
