Laboratory Report: Unit 6

Introduction & antiophthalmic factor; Hypothesis The purpose of this experimentation was to form a better understand of osmosis. We conducted an experiment using dialysis saucers make full with dissimilar solutes and recorded the process that moved the water and or solute into or unwrap of the radixs. Additionally, we postulated that pocket book 1 containing 10 ml of 10% saccharose in the distilled water beaker provide have a hypertonic solution beca enforce the saccharose go away move into the beaker. In conjunction with the previous statement, we believe bag 2 (10 ml of dH20 in a 10% sucrose beaker) will be come a hypotonic solution and bag 3 (10 ml of 10% sucrose in a sucrose beaker) will remain a isotonic solution. Materials & Methods: 1. localize the 400ml beakers in the lab, you will need three. Then with the exit hold of writing tool, pit the beakers 1-3. 2. Locate the beaker you labeled 1 and add cc ml of distilled water. Then add 200 ml of the 10 % sucrose to both beakers labeled 2 and 3. 3. Find the dialysis subway in the lab, make true it has been underwater in water and apprehension 3 tubes. Also you will need to need half-dozen pieces of cotton strings and edit them to the continuance of four inches; you will need this to tie the ends of the tubing. 4. Take oneness end of the tubing and twist it like a sugarcoat wrapper and give the string to tie it tight.

Then use your fingers and rub the other end until it opens. Repeat this two much times 5. intention a pipet to put 10 ml of the appropriate solutions in for each one bag: pocket 1: 10 ml 10% sucrose Bag 2: 10 ml Distilled Water Ba g 3: 10 ml 10% Sucrose 6. toy as muc! h air as possible come on of the tubes and tie the remanding open sides shut. 7. nettle sure to cut the extravagance string hanging off of each bag. 8. Locate the digital balance scale and weigh each bag. Make sure to dry the bags before weighting them and also correct out the scale before weighing each bag. 9. by and by put down the mass of each bag dig up your beakers and place each bag in the...If you want to get a spacious essay, order it on our website: OrderEssay.net
