  • The Boiling Point 2-Hexaanol And 3-Methyl-1-Hexanone

    The boiling point of an organic compound determines its structural features and physical properties of the compound, which helps us to name the characteristics. Boiling point defined as the “temperature at which the vapour pressure of the liquid is the same as the pressure of the atmosphere on the liquid surface”. (Mahaffy, P, Bucat, B, Tasker, R, Kotz, J, Treichel, P, Weaver, G, McMurry, J 2011). The boiling point 1-hexanol, 2-hexanone, 1-pentanol and 3-methyl-1-butanol are represented in the chart above as they are approximately; 157ºC, 127.6ºC , between 137 to 139ºC and 131.1ºC respectively. The difference in the general trends of the molecules affects on the boiling point; the molecular surface area of the compound influence by the strength…

  • Simple Distillation Essay

    Distillation, described from About Education, is the process of separating liquids with 2 different boiling points. Distillating requires heating and cooling of liquid components to eventually purify the mixtures. In distillation, heat is added to vaporize the liquid with the lower boiling point and this vapor gas bubble is condensed back into its liquid form, where it is then collected in a receiving flask or a graduated cylinder. Multiple distillations and collections, depending on the types…

  • Thermal Energy And Thermal Energy

    This is the consequence of a decrease in the specific heat capacity of the solution compared to pure water. The specific heat capacity drops because the specific heat is lower for salt. Hence, when water is mixed with salt the specific heat value drops. In other words, it takes less energy to raise the temperature of the salt water by 1K than pure water. This means that the salt water heats up faster and eventually gets to its boiling point first. The heat capacity of NaCl has been found to be…

  • Fractional Distillation And Gas Chromatography Lab Report

    the two unknown volatile liquids. Once the unknown mixture was successfully fractioned, gas chromatography was used to help determine the identity of the two unknown liquids. Fractional distillation and simple distillation both take advantage of two major physical properties to separate liquids. Specifically, boiling point differences and the identity of the vapor phase of mixtures. However, one must utilize the correct distillation based on the conditions presented. If a mixture of volatile…

  • Essay On The Boiling Point Of Pentane

    methods. For example, boiling, freezing and the physical properties were used to help identifying the unknown compound. In the experiment the boiling, freezing and the physical properties were measured. Furthermore, a table of a given data was used to help identifying the compound by comparing the boiling points, freezing points and the physical properties given in the lab manual on pages (50-52). Identifying a compound can be crucial in real life situations especially when helping others. For…

  • Difference Between Simple And Fractional Distillation

    Simple distillation was used for a liquid whose boiling points is 25 degrees Celsius over the other liquid, whereas fractional distillation is used for liquids with boiling points that are closer than 25 degrees Celsius apart. To obtain the highest percent ethanol, fraction distillation is proven to be the most effective. Because the 2 liquids have a boiling point difference of about 25 degrees Celsius, we used both simple and fractional distillation to remove the ethanol from the water.…

  • The Pros And Cons Of Ice Skating

    First off, water has a very high boiling point, one hundred degrees Celsius, relative to its small molecular weight at roughly eighteen grams. Water requires more energy to break hydrogen bonds before it can boil. Freezing works the same way as boiling, but in reverse since it is going to colder temperatures, zero degrees Celsius to freeze, rather than hotter. These extremes in freezing and boiling points allow the molecules to freeze or boil very slowly. Another unique property of water is…

  • Boiling Point Lab Report

    This experiment examined the boiling process and the effect of added ingredients. Purpose of this experiment is to understand boiling process as well as the factors that affect this property. The objective of this experiment is to investigate the appearance and temperature of range of water that is lukewarm, scalding, simmering and boiling point. On top of that, we also need to determine the factors that boiling temperature of water alone and with various ingredients added. In this experiment,…

  • Hexane And Toluene Experiment

    Purpose The purpose of this experiment was to collect three different fractions of a mixture of hexane and toluene at differing temperatures. From there, the fractions would be measured via gas chromatography to discover the percent composition of hexane and toluene in each fraction with the ultimate goal of having one fraction with mostly hexane, one with mostly toluene, and one with an even mixture of the two. Along with this, there is also the goal of redistilling one of the fractions in…

  • Catechol Oxidase Lab Report

    Introduction: Enzymes have a huge effect on the human body and other organisms. Enzymes are catalysts that are used to accelerate the reaction process by lowering the activation energy. For this experiment the catechol oxidase was extracted from potatoes. The enzyme is called catechol oxidase because the oxygen is reacting to catechol. Catechol oxidase causes the browning of the fruits and vegetables because the compound is toxic to the bacteria. The purpose of this experiment is to…
