Product Details

Introduce the basic concepts of osmosis and diffusion with this involving laboratory activity. Using a colloidal solution of starch and sodium chloride students will clearly observe the process of dialysis, observe diffusion through a semipermeable membrane, separate an inorganic salt from a colloid and test for the presence of chloride ions and starch. Enough materials are supplied for 30 students working in pairs. Detailed student and teacher materials provided.
