Role of a selective permeable membrane in osmosis

Answer 1

A selective permeable membrane is a type of membrane that allows certain molecules to pass through it while blocking others. In osmosis, a selective permeable membrane is used to separate two solutions of different concentrations. The membrane allows water molecules to pass through it, but not the solutes. This causes the water molecules to move from the area of lower solute concentration to the area of higher solute concentration, resulting in an equalization of the concentrations on both sides of the membrane.
