4. Figure 2.7 shows a selectively or differentially permeable membrane. This is a thin sheet of material that selectively allows certain molecules to cross but prevents others from crossing it. The membrane in this figure is permeable only to water molecules Differentially permeable membrane 10% chloride ions 8% chloride lons Figure 2.7. Diffusion of water. What percentage of water is there in the left part of the container? What percentage of water is there in the right part of the container? Where is the water in higher concentration, on the left or right side? Draw an arrow to indicate the net direction of movement of the water molecules
