    The purpose of this lab was to perform the condensation of acetic acid with isopentyl alcohol in the presence of sulfuric acid. Isopentyl acetate was formed from this reaction and this compound has the distinct smell of bananas. This reaction is known as Fisher Esterification. From the final product, the final mass was used to calculate the percent yield. Finally, the IR spectrum was obtained from the final product in order to determine if the reaction went to completion or not. To a 5mL conical vial with a magnetic stir bar was added 0.8mL isopentyl alcohol, 1.6 mL glacial acetic acid, and 5 drops of sulfuric acid. This vial was connected to a condenser. The vial was heated to reflux for 50 minutes. The time was taken once the solution began to reflux. The solution remained colorless liquid after it refluxed for 50 minutes. In addition, the reaction had a slightly odor to the bananas. Once the vial was cooled to room temperature, the vial was placed in an ice bath for 3 minutes. After, 1.0mL of ether was added to the vial and the volume was adjusted to…

    back high in to the atmosphere into freezing temperatures (This is an updraft). The drop begins to fall again gaining more moisture and getting bigger. This happens over and over again until the drop is big enough to fall down to the surface as hail. So we know what rain is like on our planet. What is it like on other worlds? Let 's take a trip to the first stop in our adventure, the planet Venus. Venus is Earth 's twin. It closely resembles the size of our home. Venus is the hottest planet in…

    for re-use. Some of these technologies generate liquid effluents, solid wastes, and air emissions during the regenerating process. The types of wastes, effluents, and wastes vary with the technology and processes used, and the environmental control methods [CEPA, 1994]. Liquid effluents are required additional treatments before they can be reused for cooling or discharged to a sewer system [CEPA, 1994]. Solid wastes generated from the regenerating process include various types of sludge (e.g.,…

    reactions. To study the % yield of copper in the copper cycle, the initial mass and final mass of copper was measured. The chemical reactions involved in the copper cycle are dissolution, precipitation, dehydration, and oxidation/reduction. First, copper was reacted with in a beaker to form (aq) and . The purpose of the dissolution reaction is to convert the copper into solutes in the forms of dissolved components. The was reacted with NaOH to form the precipitate (s). The purpose of…

    achieve this aim, titration of an unknown solution of sulphuric acid (around 0.2-0.4 mol) and sodium carbonate (0.2 mol) using methyl orange as an indicator. 1. Introduction Fossil fuel is formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years. “As the mud sediment was buried by more sediment, it started to change into…

    While the list had a very large number of different materials that were located in the shop, I only will list the chemicals that would present an industrial health hazard to an employee using them and chemicals that are used in every battery repair. Since some repairs use different chemicals and different processes, I decided to narrow it down to a very basic battery repair that would be done at the Fairmont shop I visited. First would be sulfuric acid, which is used in the cells of the battery…

    In the first step of the cycle, about 5 mL of 6 M HNO3 were added to the beaker containing the 0.2471 grams of copper turnings. In the reaction that followed, the copper turnings dissolved as the solution turned green and eventually light blue accompanied by a small sizzle. The chemical reaction that took place here was Cu(s) + 4 HNO3(aq)  Cu(NO3)2(aq) + 2 NO2(g) + 2 H2O. This was a redox reaction because oxidation occurs. This was proven from the reaction because copper was oxidized by the…
