Molarity Of Sucrose Experiment

Decent Essays
Based on the data collected, the color of 0.0M is clear, 0.2M is blue, 0.4M is yellow, 0.6M is green, 0.8M is red, and 1.0 is black. The relationship between the change in mass and the molarity of sucrose within the dialysis bag is directly 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 the bag.

    Title: Alexandra Whitaker, Ms.Dayton, 12/23/16, 2.03 lab permeability Objective(s): The main purpose is to find out if plastic bags are permeable to starch and, or, iodine. Also, to find out wither potatoes are hypotonic, hypertonic, or isotonic by testing the different amounts of sucrose solutions Introduction: The necessary background information needed for this lab is the definition of osmosis, diffusion, active transports, passive transports, permeability, concentration, tonicity, and to now the scientific concepts of hypotonic, isotonic, and hypertonic. Hypothesis: For part 1 my hypothesis is: That the starch will diffuse across the plastic bag and react with the iodine and will have a color change to the water to imply the reaction…

    While he wanted to achieve a solution of 400 mL, he ended up with a solution of 420 mL because he did not take into account the volume that the solute (sucrose) would take up within the solution. This additional volume would thus also change the concentration; however, even if the actual concentration amounted to 400 mL, he would still have not obtained the 4M he assumed he was creating. This may be due to guessing, but he may have also assumed that by adding 400 mL of water, that would make the solution 4 M, regardless of the amount of solute he added into the mixture (If he wanted a 3M solution, he may have thought he could add 300 mL of deionized water). Because of his error, he ended up with a solution with a much smaller concentration. Therefore, when the student wants to create a solution of certain concentration, he needs to know either how much solution or solute he wants and then calculate for the other component in order to achieve the desired concentration.…

    The iodine lab demonstrated the concept of diffusion, the movement of molecules move from a higher concentration to a low concentration through a semipermeable membrane. In the experiment, we observed a beaker filled with distilled water and Lugol’s iodine solution enter a bag filled with glucose and starch solution through the semipermeable membrane provided by the dialysis tubing. While the beaker remained the same color throughout, the solutions in the bag changed from a clear color to a light blue color due to the influx of iodine indicating the presence of starch. Although water molecules are polar, they are small enough to move across the membrane until it reaches an isotonic solution. There was also now a presence of glucose in the…

    Analysis Of Alka Seltzer

    Introduction: Alka-Seltzer is a medication used to alleviate ailments such as heartburn and acid indigestion1. The ingredients that the tablet is made up of helps explain the name of the medication, the sodium bicarbonate is used to balance stomach acid, help spread the aspirin which allows the speed of absorption to increase, and reacts with citric sodium which produces carbon dioxide2. One initial observation of the Alka-Seltzer tablet and water is that when the tablet was dropped into the water, it began to fizz and make the water look like a carbonated drink such as Sprite. Carbon Dioxide is the gas that humans exhale and what is produced with Alka-Seltzer and water react, the chemical equation of the reaction is, (H2O + C6H8O7 + 3NaHCO3…

    With the before and after measurements in two graphs, one can easily figure out that no matter which solution the bear is soaked in, it will increase to some extent. In tap water, the gummy bear started with a mass of two point eight grams and changed 217.9 percent to eight point nine grams. The volume of the gummy bear started off at 1,296mm^3 and change 617.6 percent to a volume of 9,300 grams (Table 1). In the cup is sugar water, the gummy bear went from a mass of two point seven grams to seven point three grams with a 170.4 percent change. The volume of that gummy bear increased by 420 percent by going from 1,350mm^3 to 7,020mm^3 (Table 1).…

    Observing Osmosis

    The weight of the tube increased from 12.3 grams to 13.0 grams in 15 minutes; however, in the next 30 minutes, it decreased from 13.0 grams to 12.5 grams. The bag could have been weighed inaccurately before the weigh in by having water on the tube, or the scale itself, or the scale itself could have been misread. Since the bag was full of 10% sucrose and put in a beaker filled with 1% sucrose; the water should have rushed into the tube where the higher concentration was making the tube swell. The results of bag D supported my hypothesis that the water would rush into the tube where the higher concentration was; therefore, the tube would be hypotonic, and the tube would swell.…

    Diaper Lab

    The purpose of the diaper lab was to see if the concentration of solutes in a solution has an effect on the amount of liquid absorbed by a diaper. The experiment tested how well the diaper would retain liquids with a different solute concentration. The hypothesis driving the experiment was if a hypertonic solution is added to a diaper, then the diaper will be less absorbent because the water will be drawn out of the sodium polyacrylate (powder) in the diaper due to osmosis. Sodium polyacrylate is in most diapers and is toxic, yet incredibly absorbent polymer. Osmosis is the diffusion of water across a cell membrane.…

    The experiment that will be tested will determine if lactase can break down sucrose as it does on lactose. The topic will provide an explanation of why intolerants use sucrose as its substitute. In addition, the conclusion of the experiment will provide an explanation to seek if enzymes are highly specific for one certain molecule. Again, the experiment will be tested to answer the problem if lactase can break down sucrose as it does on lactose. However, if lactase is an enzyme that has a specific substrate, then it can not break down the disaccharide of sucrose.…

    Simultaneous hydrolysis and fermentation (SHF) of sweet sorghum juice is a multi-step process and interactions between enzymes inside the yeast and the complex substrate. In addition, SHF also undergoesmechanisms by the product and other components inside the substrate. The process, interactions, and as well as inhibition mechanism of SHF are not fully understood. A modified kinetics model based on those reported by Philippidis [24] and Shadbahr [17] were used in this study to quantify the sucrose hydrolysis and sugars fermentation. However, the original version of kinetics model [24] was also used as for the comparison.…

    If these two values were removed, the overall trend of the % change in mass in different concentration solutions would be a negative linear relationship as predicted. These two values are further proved unuseful to determine the osmolarity of the potato because of the large spread of the error bar in 0.1M, where there is a huge range of values that were found. There is a large skew into the positive % change in mass area, which shows that some values for the 0.1M were obtained correctly, however the majority of the trials received contradictory data to the expectation of a positive % change in mass. Additionally, by looking at other studies that conducted similar experiments using potatoes, their results showed similar trends for % change in mass and increasing molarity. Therefore, if these two values are removed and a linear equation is used (figure 5), the x-intercept (where the % change in mass is zero) is the estimated value of the molarity where the solution is isotonic to the potato, around 0.229M.…
