Osmosis

Investigation of Osmosis in Quails (Coturnix japonica) Egg Research Question What is the solvent of different intentness of atomic number 11 hydroxide event on de-shelled quails egg? The preoccupancy of sodium chloride used is 0%, 5%, 10%, 15% and 20%. How does the different submergence of sodium hydroxide issue affect the change of potful of quails bombard when the nut are immersed in for each one solvent and left wing for more(prenominal)(prenominal) than 24 hours? Variables variablesMethod of Controlling self-supporting closeness of sodium chloride SolutionThe ducking of sodium hydroxide solution prompt and used for this experiment is 0%, 5%, 10%, 15% and 20%. Dependent The average change of rush of quails eggThe initial fold 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 utmost mass by 3 Constant V ariable bulk of Sodium chloride solution Quails eggs The time taken for the osmosis play Volume used is 100 ml for all band Quails eggs are used in each vex of experiment The time is about more than 24 hours dodge 0.

1 variables involved in the experiment Hypothesis When the dousing 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 closeness to a region of high solute immersion. The increase in dumbness of sodium chloride solution from 0% to 25% signifies that the amounts of solute in the solution also increase. So water mol! ecules 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
