Solutions
molecules, like water, can pass through these holes but the passage of
bigger molecules like solute is hindered Membranes having this kind
of properties are known as semipermeable membranes (SPM) Assume that only solvent molecules can pass through these semi-
permeable membranes If this membrane is placed between the solvent
and solution as shown in Fig
