Final Solution

for the potato slivers were slightly stiff and high in flexibility. After leaving the 10 mL sucrose concentration solution for 45 minutes, the results show an increase in appearance, and flexibility of each individual potato. The qualitative observations from the initial results show that the potato cells have a flavescent colour with rigid texture. Also, the observations for the final results shows that the colour of the potato slivers were cream. The potato at the sucrose concentration 0.0 M…

Different Concentrations of Saline Solutions Impacting The Mass of The Baggies Research Question: Will the different concentrations of the saline solutions impact the mass of the baggies due to the effect of osmosis. Independent Variable: The concentration of saline in each solution. Dependent Variable: The mass of the baggies(g) What needs to be controlled: The type of solution in bags. The amount of solution in cups…

Introduction: All living organisms require the process of osmosis in order to live. When there is a semi-permeable membrane separating differing parts of an aqueous solution, the fluid will flow from the section with the higher osmotic pressure to the section with the lower osmotic pressure (HammelSchlege2005). This happens because the solute molecules diffuse toward the fluid with a lower concentration and the solute molecules drag the water through which they diffuse (HammelSchlege2005). This…

authoritative figure that were at odds with the participants expected moral values. These series of experiments, started in July of that year, came three months into the trial of Nazi SS-Obersturmbannführer Adolf Eichmann for his part in organizing the "Final Solution to the Jewish Question". The ability and capacity of mankinds capability to inflict pain and harm on fellow human beings was being scrutinized by the world and it is this capacity that…

variable was the zebrafish embryos after they were exposed to the C4. In addition, 2 controls were set up, containing a ocean/embryo solution, and the control was used to compare the effects between the solutions containing C4 and the solutions containing no C4. Furthermore, 2 controls were used because 2 experiments were conducted one containing a larger solution of C4 and the other containing a trace amount of C4. The hypothesis stated that if the zebrafish embryos were exposed to…

The more precisely the cubes can be cut, the better Spill 96 cm3 of water in the beaker Add 4 grams of the NaOH solution in the beaker that contains the water Put the four agar cubes into the solution Turn on the timer as soon as the cubes are in the beaker Do not take out the cubes for the following 10 minutes. In the meanwhile, observe the temperature Once the 10 minute has been reached, take out the…

Discussion: Through experimentation, it has been determined spectroscopy provides valuable information on the absorbance behavior of triclosan in a solution. It acts as a viable way to measure the concentration of triclosan in a mixture. The data obtained using spectroscopy showed the soap sample contained 0.461% triclosan by mass. This coincides exactly with the information on the antibacterial concentration found on the bottle of soap. When using the spectroscopy method as a simple procedure…

proportional. When the mass percentage increase, so does the molarity. This is because the molarity of sucrose in the bag determines the amount of water that would either move in or out of the bag. If all the bag were to be placed in 0.4M sucrose solution instead of distilled water, bags that have molarity greater than 0.4 would have an increase in mass because water move into the bag to equalize the concentrations. Bags that has molarity less than 0.4 would lose water because water move out of…

1) Create 6 different 10cm3 concentrated solutions, using Table A 2)…

There were many observable factors when investigating osmosis in potatoes. Four different solutions were created (distilled water, 1% salt (NaCl), 3% salt and 5% salt. The potatoes were sliced until they were 3cm long, each test tube contained 3 strips of potato cores and a different concentration. The potato strips were weighed and the results recorded. The potato cores were left in each solution for 24 hours. Once the test results were collected the data was averaged and placed into a graph…
