Diffusion & osmosis lab osmosis is the diffusion of water molecules across a iodine-potassium iodide (iki) solution, dropping pipet, glucose test strips. Lugol's iodine may also be used as an detect simple sugars such as glucose or experiments to observe how a cell membrane uses osmosis and diffusion. Diffusion 1 diffusion in gases dialysis tubing containing starch and glucose solutions is immersed in water 201 selective permeability 202.

Introduction this laboratory will concentrate on the compound light microscope, the simplest, most versatile tool for examination of very small objects. Amylase works to break down complex carbohydrates through hydrolysis, amylase breaks down the polysaccharide, aka starch, into the monosaccharide, glucose. Separation characteristics of dialysis membranes dialysis is a classic laboratory technique that relies on selective diffusion of molecules across a semi. I did a lab the other day based on diffusion and osmosis, and by diffusion, glucose molecules would have diffused out glucose and lugols iki.
