osmosis :: essays research papers
The following is a short sample from this gather of coursework... els of sucrose stem to distilled piss ( behold metre table above) and I fit(p) separately of the mixtures into the correct beakers. 5. Then I weighed altogether the tater chips on an electronic balance (see results) and recorded the results. 6. I placed 5 pieces of white potato vine into distributively beaker and left them for approx 36 hrs. 7. aft(prenominal) this time I run place out the solutions from the beakers and I c arfully placed them in order of mebibyte on a paper towel. 8. I dried the potato chips mildly and thusly weighed each potato piece and recorded the results. 9. As I had special(a) time I made a second test and besides recorded those Results Molarity (M) Starting weightiness (g) (Results 1) Final Weight (g) (Results 1) parting flip-flop (%) (Results 1) Start Weight (g) (Results 2) Final Weight (g) (Results 2) theatrical role Change (%) (Results 2) These values clearly support my prediction, and even though on that point are some anomalous results, there is an overall negative propensity across the whole set of results, proving them accurate. Analysis of Results The sucrose concentration of the solution into which the potato tissue is placed affects to what degree it grows or shrinks. As you fag see from the graph the results show a clear negative correlation, a very obvious inversely proportional trend. From this a conclusion bottomland be drawn. When the water concentration is high, the potato gains water, as seen by the 0.0 molarity solution. When the water concentration is low, the potato loses weight and therefore decreases in mass, as seen in the 1.0 concentration solution. This proves my hypothesis correct. The results were quite widely ranged, as seen on the graph, wittiness ......Aim To see how concentration affects osmosis on a potato. throw I will first make a prediction use the cognition I own on osmosis and I will thence deal out t he investigation to prove whether concentration affects osmosis in a potato. apply my results I will then try to run into a figure and prove my prediction to be correct or incorrect. After I have done that I will try and find ship canal in which I could improve the experiment and extend the investigation. manner stolon we will cut out 18 pieces of potatos from the alike(p) potato using a borer so that we have all the potato strips at the same length and same mass.osmosis essays look for papers The following is a short sample from this piece of coursework... els of sucrose solution to distilled water (see molarity table above) and I placed each of the mixtures into the correct beakers. 5. Then I weighed all the potato chips on an electronic balance (see results) and recorded the results. 6. I placed 5 pieces of potato into each beaker and left them for approx 36 hrs. 7. After this time I drained out the solutions from the beakers and I carefully placed them in order of mola rity on a paper towel. 8. I dried the potato chips gently and then weighed each potato piece and recorded the results. 9. As I had extra time I made a second experiment and also recorded those Results Molarity (M) Starting Weight (g) (Results 1) Final Weight (g) (Results 1) Percentage Change (%) (Results 1) Start Weight (g) (Results 2) Final Weight (g) (Results 2) Percentage Change (%) (Results 2) These values clearly support my prediction, and even though there are some anomalous results, there is an overall negative trend across the whole set of results, proving them accurate.

Plan I will first make a prediction using the knowledge I have on osmosis and I will then carry out the investigation to prove whether concentration affects osmosis in a potato. Using my results I will then try to find a pattern and prove my prediction to be correct or incorrect. After I have done that I will try and find ways in which I could improve the experiment and extend the investigation. Method First we will cut out 18 pieces of potatos from the same potato using a borer so that we have all the potato strips at the same length and same mass.
