Osmosis and Diffusion Lab

        The purpose of this testing ground was to observe the rate of osmosis and diffusion, as tumefy as the effect of molecular(a) size of the particles on this rate. standard atmosphere division I of the lab was a demonstration of osmosis and diffusion, that dealt with raisins in contrary liquid environments, each with a disparate preoccupancy of sugar. section IV of the lab was using the same brain as the demonstration, by putting objects in different engrossments of a contentedness; in this case elodea leaves in coarseness water. In both cases, the objects in a greater concentration of the snapper were stripped of their water. However, where there was a little or no concentration of sugar or salt, the objects did not stand their water, and in the case of the raisin, became saturated with excess water. portion II of the lab dealt with the rate of osmosis, and how molecular size was a fixings on it. The purpose was to see how easily molecules of smaller diameter, which were starch molecules, would throttle through an artificial membrane, as opposed to how severe it would be to pass through in the case of larger molecules, which were IKI molecules. Results were that the smaller centre passed though the membrane easily and quite a quickly, and the larger mall did not penetrate the membrane whatsoever. Part trinity of the lab was to view the effect of molecular size on the rate of diffusion. Two substances, both being of different molecular size were placed in the same environment.

Results were that the substance with the smaller molecules, diff used farther away from where it was placed t! han did the substance of greater molecular size in the same count of time. The patronage of this lab is Osmosis and Diffusion. Both these terms deal with the expatriation of... I feature looked at this essay and this would definatly be a B+ to A lab idea. The data is very finish up and whatever is create verbally is very concise and to the point. provided next time the exploiter should post the lab questions with the answers that the report offers.
