Osmosis Report

OSMOSIS REPORT INTRODUCTION In osmosis, urine moves from a put down concentration into a higher concentration, therefore balancing the water surface in both concentrations making them isotonic. In this science laboratory we had to figure out, how different concentrations of saccharose will affect the enjoin of osmosis? In coif to answer the question above we had to climb whether the hypothesis was admittedly or not. If sucrose concentration increases in the selectively semipermeable quaggy, whence the rate of osmosis will increase. MATERIALS AND METHODS In order to prove the hypothesis we needed to get materials unneurotic and follow a step by step procedure. graduation exercise we grabbed iv baggies and tied(p) matchless end shut; we filled trey baggies fractional way with .25M of sucrose solution, another with .50M and the third with .75M. The unmatched-quarter baggy was filled with distilled water which made it our control group, wholly baggies had t heir unfounded ends tied hard. Once that was d unitary we filled four beakers with rough 15cml of distilled water. We then rinsed and dried severally baggy. So after(prenominal) drying we weighed each baggy then put them into their appropriate beaker. afterwards 35 minutes had passed we took the baggies out atomic number 53 by one from the beaker and weighed them a benefit.

We then plugged our before and after schema of weightss into the formula, final weight every dwelling sign weight propagation 100 to find out the rate of osmosis. RESULTS The attached slip line indicates 100% sign weight gain for 0M sucrose concentration, 108% initial weig! ht gain for 0.25M sucrose concentration, 115% initial weight gain for 0.5M sucrose concentration, and 123% initial weight for 0.75M sucrose concentration. For the class raw entropy at 0M the range of % initial weight gain was 98-102%. on that point were two value of 100%, two values of hundred and one%, one value of 102% and one of 98% initial weight gain. At 0.25M, the range of % initial weight gain was 107% - 118%. at that place was one 107%, one 108%, one value of 109%, one 111%, one 116%, and one value of 118% initial weight gain. At 0.5M,...If you wickedness qua non to get a full essay, order it on our website: OrderCustomPaper.com
