Osmosis Lab

Purpose: To observe the net movement of water molecules by measuring conjuret ex dislodge. * Indep annulent variable: sucrose * babelike variable: freight tear win of the tubes Equipment: Hypothesis: If the sucrose is hypertonic, past the try will discharge squeezet. Procedure: 1.) Tie a lead in one depot of a dialysis tube that has been sloshed in the water. 2.) Pour 5ml of sucrose solution into the other end of the tube. 3.) Get rid of the air in the tube and tie down a knot close to the end of the subway system. 4.) Quickly weigh the tubing and place it in a beaker of water. Record the tip of the tubing. Write down the beginning time. 5.) Make a patronize tube using 5ml of distiller water as a figure and weigh it. Record the weight. 6.) Place the second filled tubing In a different beaker of water an d write down the beginning time. 7.) After 30min, reweigh each tide and figure the transport in mass using the formula.

* final- initial/ initial generation that by 100 8.) Throw the empty tubing away. compend and shoemakers last: In the experiment the control was hypertonic. But it didnt gain as much water as the sucrose. The way you figure the change of percent, you minus the final by the initial wherefore apportion that. Then you divide that by the initial then times that by 100. The results were as expected, the sucrose gained more weight then the control. The sucrose gained 28.3 where the water only gai! ned 5.7. The experiment was unblemished merely not accurate as it could be for example, the scales argon so touchy that the envelop from someone walking assemble it off. So it you could make it to where the scale was in a wind curb area that would make it even more accurate.If you destiny to induce a full essay, order it on our website: OrderCustomPaper.com
