6.03 Calorimetry Lab Report
To begin the experiment, the unknown needs to be determined as an acid or a base by using litmus paper or a pH strip. For the rest of the experiment, if the substance is being handled, gloves and goggles must be worn. Use a clean and dry Erlenmeyer flask and weigh it. Then, some of the unknown will be measured and poured into the flask. Also way the flask and the unknown. Add distilled water and phenol saline to the flask. Set that aside to prepare the biuret. Choose the substance that will be used as the titrant which will be put into the biuret. Clean out the bureau with the titrant by draining it through the biuret and discarding it. Then, but the titrant in the biuret and drain some of it to make sure there are no air bubbles in the stopcock.

    Besides, the conical flask should be stirred all along the titration to ensure the two solutions can be mixed evenly. Furthermore, repeat the experiment for getting the average readings to ensure the accuracy of the experiment. Lastly, keep the eyes in level with the liquid surface while reading the burette to prevent parallax…

    Figure 1: Titration curve of 0.160 grams of an unknown diprotic acid that was dissociated in distilled water. Shown is the pH versus the volume in milliliters of 0.1 M NaOH, a strong base, added to the solution. The initial pH reading of the solution was a pH of 2.60. Although the pH of the ½ equivalence point was unknown, it could be estimated by halving the volume of NaOH used at the first equivalence point. At the first equivalence point, 13.63 milliliters of NaOH had been added to the unknown acid solution.…

    With my test result, it clearly shows that the concentration of sulfuric acid is 0.05 mol/dm3 using the concentration equation, c= n/v. 25 cm3 of the volume with sodium hydroxide is equal to 0.025 dm3 by dividing a thousand with cm 3 and multiply it with 0.1 mol/ dm3 which is the concentration of sodium hydroxide. With the ratio between sulfuric acid and sodium hydroxide is 1 to 2 so, 0.0025 should be divided by 2 and 0.00125 moles of sulfuric acid is come out. Finally, using c = m/v, 0.00125 mole/0.025 dm3 and the answer for concentration of the acid is 0.05 mole/ dm3We started our experiment with the initial volume of 0 cm3 in four trial and all of the trials ended up with the final volume of 25.00cm3 All four indicators with phenolphthalein…

    Class average for a 80 and 120 drop count was recorded to be 0.041+/- 0.005 mL/drop. If a graduated cylinder is not available there is another way of adding more of the solution. The disposable pipet can transfer 0.5mL of the solution to the chemical reaction. When comparing a 10mL graduated cylinder, a 100mL beaker, and a 50mL graduated cylinder, the most precision peace of glass wear would be the 10 mL graduated cylinder with the true volume of water (calculated), class average, and uncertainties being 9.7896 +/- 0.05mL. The 50mL graduated cylinder comes in second place with a true volume of water(calculated), class average, and uncertainties being 50.0001 +/- 0.22mL. The third peace of glassware coming in as the least accurate would be the 100 mL beaker with a true volume of water(calculated), class average, and uncertainties being 59.9999 +/- 0.82mL.…

    Your teacher will demonstrate for the class the reaction of metallic copper with concentrated nitric acid, HNO3. This must be done in the fume hood. (Caution: Avoid breathing poisonous gases. Avoid contact of skin with nitric acid. It burns skin and clothing.) One student will be asked to feel the side of the demonstration beaker and report to the group. The products formed are copper(II) nitrate solution, Cu(NO3)2(aq), and nitrogen dioxide gas, NO2(g).…

    In the first week of the experiment, the goal was to find the moles of NaOH, as well as a 0.1 molarity, while in the second week to goal was to determine the percent KPH in the sample. The first week titrations were successful and had very similar amounts of pink, which shows the precision of the results. The best trials were in the sample trial and the second and third trials. The average molarity calculated for the first week was 0.1017 M. This very close to the 0.1 M that was supposed to be made.…

    In the first process of the lab, you measure the mass of water transferred from a buret to a beaker, to determine the experimental mass of the water, and the volume of the water collected. We measured the temperature of the water so we could calculate the density of the water, which enabled us to calculate the actual volume of water, by using the density and the measured volume of water. To determine the percent error, we had to subtract the actual volume of water by the experimental volume of water transferred from the buret to the beaker, and then divided it by the actual volume and multiplied it by 100. In the second process, you perform the same steps you did for the buret, but instead, you use a 5.00mL or 10.00mL pipet. You repeated each…

In our laboratory, we determine the number of purified cells in a Neubauer-improved, bright line chamber with V-slash with a depth of 0.1 mm and a counting area of 0.0025 mm2 from Marienfeld (Lauda Königshofen, Germany, PN # 0650030). 2. For determination of the final cell yield, mix a 10 µl aliquot of the purified cells (Figure 9D) with 10 µl of trypan blue solution (Figure 9E).…
