Osmosis

INVESTIGATING OSMOSIS EFFECT OF SALT CONCENTRATION ON jumble spud CELLS Aim: The aim was to investigate how salt density affects osmosis in tater cells. To reach a conclusion, i followed the manner which was demanded in the handout supplied by the teacher. What followed was collecting the info from divergent groups to perplex more set. After that, I organised the data and began my calculations which I divided into different steps to train it more comprehensible. look 1 - Organization of data gained from my investigation as well as the different groups into tables for better orientation - locoweed is in Grams, M = preoccupancy (NaCl + H2O) grade 2 - weigh the difference among the jalopy in front and after for any level of assiduity (M) and for every group - (mass in advancehand mass after) - Values are in grams STEP 3 - I took the results from step 2 and rearranged them based on the levels of salt assiduousness so I tin later use it to give away an median(a) of the values in order to make a represent STEP 4 - In this step I calculate the average values from the values gained in step 3- -E.g.: (-0.55+(-0.2)+(-0.34)+(-0.39)+(-0.49)+(-0.

51)) /6 STEP 5 - Making a represent from the values gained in tonicity 4 - X axis = NaCl soaking up - Y axis = difference between mass before and after Weaknesses of my investigation: - Potato age and species - confused potato rectangle sizes - Temperature of water - Amount and conce ntration of water Conclusion: ! From the graph we can see that NaCl concentration does effect osmosis. The Before-After difference increases with concentration until the conc. of 0,8M (0,67g) is reached from there it began to decrease until it reached 1M (0,37). If I were to repeat this investigation, I would canvass to fade most of the weaknesses as possible and opt to do it in a more stable environment. I would reign the water...If you fate to get a full essay, order it on our website: BestEssayCheap.com
