  • Ethyl Cinnamate Lab Report

    Abstract: The purpose of this experiment was to extract ethyl cinnamate, cinnamic acid, and glucose, which are ingredients in the candy, Red Hots. The experiment began with 0.604 grams of a mixture of ethyl cinnamate, cinnamic acid, and glucose. The purity of glucose and ethyl cinnamate was measured through IR Spectroscopy. Melting point was used to determine the purity for cinnamic acid. Using the final amount for each ingredient, we determined the percent yields, which were 64.7% for glucose, 56.2% for cinnamic acid, and 38.8% for ethyl cinnamate. The melting point of cinnamic acid, tested twice, was consistent with the melting point of pure cinnamic acid. The glucose corresponded to the standard IR spectra, indicating we had pure glucose.…

  • The Melting Point Of Urea And Trans-Cinnamic Acids

    molecules, the compound that is being heated up starts to melt and become a liquid. In this lab, five different ratios of two chemical solids, Urea and trans¬-cinnamic acid, were heated up in a Mel Temp apparatus until the final melting point was achieved. Each substance started as a solid in a capillary tube and when they reached the…

  • Exp 23:: Stereochemistry of the Addition of Bromine to Trans-Cinnamic Acid

    Subject: Experiment 23: Stereochemistry of the Addition of Bromine to trans-Cinnamic Acid Introduction/Abstract: The purpose of this experiment was to carry out the bromination of trans-cinnamic acid, to determine the stereochemistry of the dibromide product of 2,3-dibromo-3-phenylpropanoic acid, and find out whether the reaction proceeds by the usual bromonium ion mechanism or some other mechanism. In this experiment trans-cinnamic acid was mixed with glacial acetic acid and stirred in…

  • Synthesis Of Pb Film

    zeolite-like structure is well known as the prototype of a number of polynuclear transition-metal hexacyanometalates with the formula, Fe4Ⅲ[FeⅡ(CN)6]3 [1,2]. It exhibits electrochemical [3–5], electrochromic [6–8], photophysical [9,10], and magnetic properties [11,12]. In particular, the electrocatalytic property among these special properties enables the potential analytical application of electrochemical sensor using the PB-modified electrode [13,14]. The reduced form of PB is prussian white…

  • Effect Of Dissolving Alka Seltzer In Different Liquids

    mixture is made up of only one uniform. The ingredients of an Alka-Seltzer pill consist of 324mg of aspirin, 1625mg of sodium hydrogen carbonate, 965mg of citric acid anhydrous, dimeticone, calcium silicate, docusate sodium, sodium benzoate sodium saccharin, natural and artificial lemon flavor, natural and artificial lime flavor. Each Alka-Seltzer pill has 445mg of sodium and once an Alka-Seltzer is dissolved in water, it turns into bicarbonate which reacts with the hydrogen from the citric acid…

  • Pool Pump Functions

    You already know your pool has a pump, but do you really know what that pump actually does? You might be surprised! What Exactly Does a Pool Pump Do? Your pool pump is the heart of your pool and without it, it would die...so to speak. Just like a human heart, your pool's heart (the pump) only has one thing it has to do which is pump water. However, that one thing serves several very important functions, such as: • Pulls the water from your pool through the skimmers and drains. • Then it…

  • Differences Between Salts And Molecules

    Salts and molecules have similar characteristics, and many differences whether we can tell by first looks or not. Testing these two only supports the differences, and many structural functions cause these differences. Since salts are ionically bonded, they have different properties and functions compared to the covalent bonded molecules. Salts have a ionic bond, and we can confirm due to their electronegativity. As you move from left to right on the periodic table you would notice that…

  • Cyanoethoxy Research Paper

    suitable N-protecting group for nucleosides (Sikehi et al., 2006 and reference theirin). A solvent-free reaction utilizing a simple low-energy ball mill apparatus was reported to convert the amino groups of nucleosides S.36, adenosine, 2-deoxyadenosine, cytidine, 2-deoxycytidine, guanosine, and 2-deoxyguanosine as well as some of their ribosyl O-protected derivatives, to the corresponding bis-N-Boc carbamates S.37 (Sikehi et al., 2006). For guanosine compounds, the carbonyl group of the base…

  • The Causes Of Mandatory Acidosis

    than anything else. It is important to take care of the body from any harm. One thing that the body is capable of is maintaining pH levels and buffers. A pH is the power of hydrogen and buffers prevent extreme shifts in pH. The blood has a specific type of buffer that is maintained at pH level of 7.4. If the buffers shifts and levels of pH go to 7 or 7.8, it can be deadly. The blood buffer contains carbonic acid which dissociates into bicarbonate acid and hydrogen ions. This equation can also be…

  • Lipids In Milk Lab Report

    The Rf values were obtained by reacting the lipids on the TLC plates with iodine, to visually show how far the lipids moved up the TLC plate. For the identification of the amount of lipids in milk, the milk was combined with an organic mixture of CHCl3/MeOH, to isolate the lipid layer. By centrifuging the organic solvent with milk the heavy lipids sink to the bottom while the water layer which contain water soluble carbohydrates, peptides and small amino acids float to the top. Since the organic…
