Molar Concentration Of Acetic Acid In Vinegar Lab Report

Decent Essays
During the experiment, our lab group accomplished the lab. The purpose of the lab was to determine the molar concentration of acetic acid in vinegar. By doing so, we let the solution drip into a beaker through a burette into the vinegar. The goal of the experiment was to slowly let the vinegar drip into the beaker and not to let too many drops of the vinegar turn the solution dark pink. If you let too many drops into the solution it will quickly turn pink but if you slowly watch from eye level, you can catch it while it’s a light pink solution. In all three trials our group successfully turned our solutions into light pink solutions. In the experiment the reactions that occurred were neutralization. Neutralization reaction means that the ratio

    Three test tubes where number 1-3, the first and second test tubes (#1,#2) where mark at 1cm and 5cm from the bottom of the test tube while test tube #3 was mark at 3cm and 7cm. Test tube #1 was filled up to the 1cm mark with distilled water and to 5cm with Hydrogen peroxide. The substance was swirl for 30 seconds and the height of the bubbles column where recorded. Test tube #2 was fill up to the 1cm mark with catalase and to the 5cm mark with hydrogen peroxide. The substance was swirl for 30 second and the height of the bubbles column where recorded.…

    This lab makes use of the reaction excess powdered calcium carbonate and different concentrations limiting hydrochloric acid in order to determine the effect of changing concentration on the rate of the reaction. Students will carry out 3 trials of 5 experiments each trial. The five different experiments are for the various concentrations of hydrochloric acid (0.2, 0.4, 0.6, 0.8, 1.0 mol/L). First measure out approximately 2 grams of powdered calcium carbonate using a weighing boat and analytical balance. Then, measure out 30 mL of 0.2 M hydrochloric acid into a volumetric flask.…

    This step means that the cyclohexane/iodine is clearly separated from the impure aqueous layer (it will be obvious because the top layers strong purple colour and the bottom layer clear colour). You must make sure you allow the two layers to separate, if they do not completely separate or the colours are incorrect then the experiment will have to be started again. 7.…

    This experiment was adding one drop of water to each of four solutions. This only diluted the chemical and did not generate any useful results. Another error was the bottle of chemical t, which was lead (II) nitrate. In the first experiment, these two chemicals had a pH that differed by 4, more than any of the other chemicals. This problem could have been due to a mistake in dilution when the chemical was being bottled, or it was outdated.…

    They will then attain five small test tubes, in which they will mix varying amounts of copper sulfate and sodium hydroxide. Once a precipitate has formed in all five test tubes they will record and analyze their observations. Fun Fact: The technique used to determine the limiting reagent in part A of this lab, is used to determine how much of a desired product can be produced, which is tremendously important in the medical field.…

    The goal of this lab was to find the molar sucrose concentration at equilibrium. Which is when the potato core and the sucrose solution reach equilibrium, so that no water is entering or leaving the cell. After collecting the data, the line of best fit never crossed the x-axis or showed where the molar sucrose concentration at equilibrium. I had to extrapolated the point at which it crossed the x-axis. This led to the data being unreliable because there is no physical evidence present that shows the psi of the solute.…

    The purpose of this lab is to practice different scientific methods, practice making different observations, and observe chemical and physical changes. What we did was measure out 4 grams of the powder and same with the little ball shaped chemicals that were solid. What happened in this experiment was when you put the liquid chemical called the acid indicator in the different types joined and formed a gas type substance. And our uncertainty was low, we had no idea if we were doing the lab right and if we were going to get the right results but we had it in the bag. We had learned new things like how to make a reaction, gas, chemical, and burn something without a flame.…

    The second test is vinegar (dilute acetic acid) to test this continue putting a small amount of each substance in each tube with 5 mL of vinegar the reaction will be bubbles. The next test will be Iodine test continue to set up the test tubes like the other two procedures, but set aside two test tubes. Drop 2 droplets of iodine in each and your reaction should be a blue substance. The last test would benedict's solutions it is performed for simple sugars the colors should change green,yellow, or brick red depending on the sugars. Repeat the steps of the other procedures and see what color the tubes…

    Discussion: The hypothesis stated that as the amount of baking soda increases, the total time of its reaction with vinegar will be increased as well. However, that was not the case during the actual experiment. As discussed previously, the results followed a small pattern but not for the whole experiment. The results can be confirmed that are very reliable, since repeated trials were done, sometimes more than three.…

    I tested it with the second drop of iodine. It was important to always get a fresh drop of the mixture from the test tube since it cooled rapidly. 14. I repeated the test at 10 second intervals until I reached the endpoint of the reaction, the point at which the mixture remained the same colour as the iodine solution. 15.…
