Potato Osmolarity Lab Essay

PurposeThe purpose of the research lab is to discover the osmolarity of the spud tissue.Background InformationOsmolarity is a concept standardized to concentration, except it is the total number of solute particles per liter. In this lab we can see osmolarity by using saccharose consequences and potato ores. This experiment displays hypertonic, hypotonic and isosmotic solutions. A hypertonic solution is a solution with a relatively higher concentration, hypotonic cis relatively lower, and isotonic is the same.VariablesConstant = size of potato coreIndependent = sucrose molarityDependent = battalion division changeSafetyFollow lab safety protocol and be careful with cork borer.Procedure1. With a cork borer, cut sextuplet cores from a potato. The cores should all be as close to the same length as possible 30-50 mm cores are recommended. 2. Before continuing, produce a table that will show the volume and mass of the potato cores beforehand and after being placed in solutions of 6 antithetical sucrose molarities. 3. Determine mass of potato cores using a laboratory balance. rule book in table. 4. Place each core in a different turn up underpass labelled with the cores identification earn and the molarity of the sucrose solution to be placed in the vacuum tube 5. Add a labelled molar solution to each test tube until core is covered. Place foil over each tube and store for 24 hours 6. On the next day, repeat step 3Conclusion/AnalysisThe osmolarity of the potato core is 0.4 M, I determined this by finding where on my interpret the percentage change in mass was equivalent to 0. This meant that there was no change in mass, the tissue and solution were isotonic, and the molarity of the solution is the same as the osmolarity of the tissue. In this lab, and all experiments, an dead on target measurement of mass was crucial to finding the correct results, trend, and osmolarity. The conclusion of this lab was based off of a negative trend on the graph whi ch could view as been skewed from inaccurate data.In order to attain more reliable data I could have done multiple trials in the procedure which would clarify my results and conclusions. Also to generate better data a more precise device for measuring the mass of the potato cores could have been used. Also the size of the potato cores could have been more constant to fabricate more accurate data. Outside of this experiment osmolarity is used in pissing tests to calculate the concentration of certain particles in urine. An osmolality test can alike be used for the blood to see the number of solutes present. These tests are indeed helpful in diagnosing and treating patients.
