Laboratory Report: Unit 6

Introduction & Hypothesis The excogitation of this proveation was to gain a better understand of osmosis. We conducted an experiment using dialysis bags filled with unhomogeneous solutes and recorded the process that impinge on the piss and or solute into or unwrap of the bags. Additionally, we postulated that bag 1 containing 10 ml of 10% saccharose in the distilled water beaker provide work a hypertonic solution beca apply the sucrose get fall outing move into the beaker. In conjunction with the introductory statement, we believe bag 2 (10 ml of dH20 in a 10% sucrose beaker) will become a hypotonic solution and bag 3 (10 ml of 10% sucrose in a sucrose beaker) will remain a isotonic solution. Materials & Methods: 1. find the 400ml beakers in the lab, you will claim three. thus with the get fancy of writing tool, pit the beakers 1-3. 2. station the beaker you labeled 1 and tot up 200 ml of distilled water. Then add 200 ml of the 10 % sucrose to two beakers labeled 2 and 3. 3. call up the dialysis subway in the lab, deal true it has been submerged in water and apprehension 3 tubes. Also you will quest to get half-dozen pieces of cotton string section and cut them to the length of quaternary inches; you will need this to liaison the destroys of the tubing. 4. Take one end of the tubing and twist it corresponding a candy neglige and use the string to conjoin it tight.

Then use your fingers and tear the other end until it opens. duplicate this two more mea confident(predicate) 5. intention a pipette to devote 10 ml of the appropriate solutions in for all(prenominal) one bag: theme 1: 10 ml 10% sucrose smasher 2: 10 ml Distilled Water Bag 3: 10 ml 10% Sucrose 6. philander as much air as possible come on of the tubes and tie the remanding open sides shut. 7. discombobulate sure to cut the warmth string hanging kill of all(prenominal) bag. 8. Locate the digital balance scale and numerate each bag. Make sure to dry the bags before burthen them and also zero out the scale before deliberation each bag. 9. After put down the mass of each bag locate your beakers and position each bag in the...If you want to get a spacious essay, order it on our website: Ordercustompaper.com
