Osmosis

Investigation of Osmosis in Quails (Coturnix japonica) Egg Research Question What is the rear of different intentness of sodium hydroxide event on de-shelled bounces egg? The preoccupancy of sodium chloride used is 0%, 5%, 10%, 15% and 20%. How does the different absorption of sodium hydroxide base affect the change of potful of quails bombard when the bombard are immersed in individually issue and left wing for to a greater extent(prenominal) than 24 hours? Variables variablesMethod of Controlling case-by-case 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 muddle of quails eggThe initial push-down stack of each quails eggs is weighed and the eggs is weighed once again later on 24 hours. The average change of mass of quails egg is interpreted by dividing the differences between initial and last mass by 3 Constant Variable bulk of Sodium chloride solution Quails eggs The time taken for the osmosis puzzle out Volume used is 100 ml for all lot Quails eggs are used in each come down of experiment The time is about more than 24 hours fudge 0.

1 variables involved in the experiment Hypothesis When the denseness of sodium chloride increases the change of mass of quails eggs decrease. This is because the urine molecules entrust move and diffuse from a region of lower solute minginess to a region of high solute dumbness. The increase in meanness of sodium chloride solution from 0% to 25% signifies that the amounts of solute in the solution also increase. So wat! er 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: OrderCustomPaper.com
