Biology Iodine Lab

The atomic number 53 scatterd by means of with(predicate) the electron tube of stiffen theme and reached an equilibrium, because the concentration of unity was higher(prenominal) in the beaker comp ared to the tube inside. The stiffen was too large to diffuse through the tube. Since, the molecules of atomic number 53 are really small, it can broaden through the semi leaky tissue layer(tube) but the starch molecules are really large so they cant pass through the semi porous membrane. So the reception only happens inside the tube because thats where starch and ace meet. When starch and iodine bond thusly the origin turns purple. The starch can pass through the membrane only through facilitated diffusion, where transport proteins would have to move the starch in and out(predicate) of the membrane.

If the starch was to be in the beaker and the iodine was to be in the tube, then the reaction would be external in the beaker and the solution in the beaker would turn purple preferably of the inside because the iodine inside the tube would move outside mixing with the starch. outcome My hypothesis was correct as I had predicted that the iodine would go in because of diffusion. The iodine did go in the tube through diffusion and starch couldnt come out because its molecules were too big to get past the membrane. The water system of rules just stayed were it originally was because the volume of the beaker nor the volume of the tube changed so much. There were no errors while doing the experiment and the results came out as expected.If you want to get a full essay, order it on our website: OrderEssay.net
