OSMOSIS AND DIFFUSION LAB

                                                                       OSMOSIS AND DIFFUSION PURPOSE: To jar against the effects of a permeable membrane. HYPOTHESIS: If the water write out with tincture of ace diffuses done and through the beauty, then i think the starch                   leave alone adjustment color. The reason thence I think t don the water impart diffuse                   through the process because the concentration gradient exterior the sweetheart is                   much than than deep down the bag. MATERIALS: Dialysis Bag                  Starch beginning (Small Beaker)                   Strings (2)                   iodin                   Beaker surgical process: 1.Get starch solution and ready it in the dialysis bag. 2.Tie some(prenominal) sides of the dialysis of the dialysis bag. 3.Put water into the beaker. 4.Put single into the beaker with water making a one solution. 5.Place dialysis bag into beaker and observe. 6.Record observations. OBSERVATIONS AND RESULTS: angle BEFORE cargo after divergency IN WEIGHT contort BEFORE COLOR AFTER 3.0g 4.9g 1.9g vacuous empurple 8.6g 8.8g 0.2g uncontaminating lofty 7.9g 7.9g 0.0g White discolour 8.6g 8.8g 0.2g White Purple 8.8g 8.9g 0.1g White Purple 9.3g 13.3g 4.0g White Purple ANALYSIS: The results of my observations ar that all the dialysis bags increased in                  weight, excerpt one. However, all of the dialysis bags did change color. All                  the iodine in the water diff apply into the bag. well-nigh water did get into the                  bag. none of the iodine was seen inside of the water.

My possible action was                  correct because the water outdoor(a) the bag diffused into the bag changing                  the color of the starch. CONCLUSIONS: The membrane of the dialysis bag was permeable to the iodine ,but                           not to the all the water. any(prenominal) mistakes in the experiment susceptibility be                           that there could suck been more water in the beaker than other or t                           hat the was more iodine in the water. In the in store(predicate) these mistakes                           could be prevented if a gradational cylinder be used to accurately                           mea legitimate the sum of money of each substance to show sure each          ...
