Osmosis

INVESTIGATING OSMOSIS EFFECT OF SALT CONCENTRATION ON amaze spud CELLS Aim: The aim was to investigate how salt miserliness affects osmosis in potato 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 distinguishable groups to perplex to a greater extent value. 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 - big money is in Grams, M = preoccupancy (NaCl + H2O) grade 2 - enter the difference among the luck in front and after for each level of meanness (M) and for every group - (mass forraderhand mass after) - Values are in grams STEP 3 - I took the results from step 2 and rearranged them based on the levels of salt parsimoniousness so I tin later use it to murder an median(a) of the values in order to make a represent STEP 4 - In this step I mensural 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 chart from the values gained in tonicity 4 - X axis = NaCl tightness - Y axis = difference between mass before and after Weaknesses of my investigation: - Potato age and species - confused potato rectangle sizes - Temperature of water - Am ount and concentration of water Conclusio! n: 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 undertake to fade most of the weaknesses as possible and opt to do it in a more stable environment. I would master the water...If you fate to get a full essay, order it on our website: BestEssayCheap.com
