Osmosis

Investigation of Osmosis in Quails (Coturnix japonica) Egg Research Question What is the proceeds of different intentness of atomic number 11 hydroxide event on de-shelled withers egg? The preoccupancy of sodium chloride used is 0%, 5%, 10%, 15% and 20%. How does the different engrossment of sodium hydroxide termination affect the change of potful of quails bombard when the nut are immersed in severally theme and left wing for more than(prenominal) than 24 hours? Variables variablesMethod of Controlling free-living closeness of sodium chloride SolutionThe dousing of sodium hydroxide solution prompt and used for this experiment is 0%, 5%, 10%, 15% and 20%. Dependent The average change of pack of quails eggThe initial raft of each quails eggs is weighed and the eggs is weighed again later on 24 hours. The average change of mass of quails egg is interpreted by dividing the differences between initial and concluding mass by 3 Constant Vari able muckle of Sodium chloride solution Quails eggs The time taken for the osmosis movement Volume used is 100 ml for all dance orchestra Quails eggs are used in each set of experiment The time is about more than 24 hours protract 0.

1 variables involved in the experiment Hypothesis When the minginess of sodium chloride increases the change of mass of quails eggs decrease. This is because the urine molecules go forth move and diffuse from a region of lower solute tightfistedness to a region of high solute constriction. The increase in tautness of sodium chloride solution from 0% to 25% signifi es that the amounts of solute in the solutio! n also increase. So water molecules will diffuse more into the solutions of higher concentration and the exhalation of mass is bigger. Water molecules from quails eggs will diffuse more into solution of higher concentration and less or no into solution of lower concentration 1.DATA COLLECTION Quantitative Data Concentration of sodium chloride solution,% concentration ±0.5mlMass of de-shelled quails...If you want to get a full essay, order it on our website: BestEssayCheap.com
