The objective of the experiment Fractional Distillation and Gas Chromatography was to determine the organic liquids existent in 30 mL of an unknown mixture. This can be accomplished by fractional distillation. Distillation is a technique that allows one to separate liquids by boiling the liquids and which removes water from its impurities. Simple Distillation separates out a liquid/solid mixture. If the boiling point is greater than 40 degrees Celsius then simple distillation will be able to be used to separate two liquids, if not then Simple Distillation cannot be used. Fractional distillation splits two liquids and transfers them to their pure form by using their boiling points. In order for Fractional Distillation to be used, the boiling point has to be less than 40 degrees Celsius. The only difference between them is that in fractional distillation a column runs to the flask while in simple distillation there is no column. Of the two main types of distillation, Simple and Fractional, Fractional distillation is the one that is used to split the liquids. To get this experiment unde...

  • Separation Challenge Lab Report

    1157 Words  | 3 Pages

    The hypothesis that was formed in this experiment was that decantation and distillation were the techniques that would be successful in separating the three layered substances. The oil on top of the mixture was to be decanted solely, and the salt and sand layers would be distilled and separated together on filter paper on top of boiling hot water. The reason that the oil is decanted is because it doesn’t mingle with the salt and sand layers, and in addition it was the top layer, which was thought to have been easy to separate first. And as for the sand and salt, sand doesn’t mix and dissolve in water compared to salt, which does in fact dissolve, so distillation was thought to be the proper solution to separating the two

    For this experiment we have to use physical methods to separate the reaction mixture from the liquid. The physical methods that were used are filtration and evaporation. Filtration is the separation of a solid from a liquid by passing the liquid through a porous material, such as filter paper. Evaporation is when you place the residue and the damp filter paper into a drying oven to draw moisture from it by heating it and leaving only the dry solid portion behind (Lab Guide pg. 33.).

  • Eugenol Oil

    700 Words  | 2 Pages

    Because of the limited amount of time the student is provided during this lab experiment, the complete amount of distillate was not collected fully due to the procedure being very slow and time consuming. The final eugenol that was isolated was not completely pure, and this is proven by the percent recovery being 110%, which is clearly higher than a 100%. This means that other substances were isolated along with the eugenol oil, such as leftover dichloromethane, which was used in the first place because the water and eugenol did not successfully separate into two layers, thus dichloromethane was added to help separate them. This is was caused percent recovery to be higher than what it should be. Heating and boiling the final solution for a longer time until all the dichloromethane is evaporated completely can easily avoid the presence of

  • Essay On Hydration Of Norbornene

    723 Words  | 2 Pages

    Hydration of alkenes is characterized by the addition of water and an acid-catalyst to a carbon-carbon bond leading to an alcohol. Dehydration is exactly the opposite in which dehydration of an alcohol requires water to be removed from the reactant. Equilibrium is established between the two processes when the rate of the forward reaction equals the rate of the reverse reaction. The alkene that is used in this experiment is norbornene. Through hydration of norbornene, an alcohol group should be present on the final product yielded what is known as exo-norborneol. Percent yield is a numerical indication of how much of the reactant was actually reacted to yield product. The equation for percent yield is shown below:

    The first procedure requires one 10mL volumetric pipette, one 50mL buret, two small beakers, one labeled “vinegar” and the other labeled “NaOH”, three 250mL Erlenmeyer flasks, labeled one, two and three, and one large beaker for waste collection. Collect 50mL of vinegar in the beaker labeled “vinegar” and record the brand and listed concentration of vinegar. Then collect about 60mL of NaOH in the beaker labeled “NaOH” and record its concentration.

  • Comparison of the Densities of Coke and Diet Coke

    In this experiment, there were several objectives. First, this lab was designed to determine the difference, if any, between the densities of Coke and Diet Coke. It was designed to evaluate the accuracy and precision of several lab equipment measurements. This lab was also designed to be an introduction to the LabQuest Data and the Logger Pro data analysis database. Random, systematic, and gross errors are errors made during experiments that can have significant effects to the results. Random errors do not really have a specific cause, but still causes a few of the measurements to either be a little high or a little low. Systematic errors occur when there are limitations or mistakes on lab equipment or lab procedures. These kinds of errors cause measurements to be either be always high or always low. The last kind of error is gross errors. Gross errors occur when machines or equipment fail completely. However, gross errors usually occur due to a personal mistake. For this experiment, the number of significant figures is very important and depends on the equipment being used. When using the volumetric pipette and burette, the measurements are rounded to the hundredth place while in a graduated cylinder, it is rounded to the tenth place.

    After performing the first Gas Chromatography, we took the organic layer, and mixed it with saturated Sodium Hydroxide. We performed this step to remove the (-OH) group from the Eugenol. The purpose was to make the water as a product, which can also be used as a solvent for the Eugenol that was ionized, for the two substances Acetyl Eugenol and Beta Caryophyllene. Again, we see the density differences in the solvents; we were able to take the organic layer. Finally, we transferred the layer into the beaker and dried, to perform the Gas Chromatography

  • Methyl Acetate Distillation Essay

    However, the measured densities lied below the accepted densities of 0.933 g/mL, 0.900 g/mL, and 0.888 g/mL for methyl acetate, ethyl acetate, and propyl acetate respectively. Refractive indices increased across all groups, including Group 6, from the methyl acetate sample to the propyl acetate sample just as expected from the theoretical refractive index values of the pure liquids. In addition, the refractive index % error calculations of Group 6 indicate that samples 1,3, and 5 produced refractive index values relatively close to the theoretical refractive indices of methyl acetate, ethyl acetate, and propyl acetate respectively. Although no distillation produces a perfectly pure liquid, the lack of relatively constant temperatures seen in the data and plots makes it unlikely that the samples collected by the class distillations had a high level of purity. Evaporation from the samples due to a lack of properly fitting test tube caps also reduced the usefulness of the density and refractive index calculations for determining the closeness of the obtained samples to the pure

    There were five test solutions used in this experiment, water being the control, which were mixed with a yeast solution to cause fermentation. A 1ml pipetman was used to measure 1 ml of each of the test solutions and placed them in separated test tubes. The 1 ml pipetman was then used to take 1ml of the yeast solution, and placed 1ml of yeast into the five test tubes all containing 1 ml of the test solutions. A 1ml graduated pipette was placed separately in each of the test tubes and extracted 1ml of the solutions into it. Once the mixture was in the pipette, someone from the group placed a piece of parafilm securely on the open end of the pipette and upon completion removed the top part of the graduated pipette.
