Osmosis lab Objective Determine the relationship between concentration of solution and osmosis Protocol Materials: six 30ml dialysis tubes, clamps, tube holders, 250ml beakers, distilled water, sucrose in 0.2M, 0.4M, 0.6M, 0.8M, 1.0M concentrations, electronic balance Six 30ml dialysis tubes were obtained. The bottoms of the bags were clamped to create bags. Twenty-five ml of each of the following were added to the separate bags: distilled water, 0.2M sucrose, 0.4 sucrose, 0.6M sucrose, 0.8M sucrose, 1.0M sucrose. The open ends of the bags were clamped, leaving enough space to keep from pressurizing the bags. The bags were dried and their mass was recorded. Six 250ml beakers were filled 2/3 full with distilled water. Each of the six bags was immersed in one of the beaker for 20 minutes. Afterward, the bags were removed,...
