    percentage amounts of ethanol in them; Listerine, Terra Fresca Wine and the last is a mixture of ethanol and water that was made by me. The three different methods compared are the redox titration method which involves the oxidation of ethanol to ethanoic acid and then titrating the residue with sodium thiosulfate, which would then be used to calculate the number of moles of ethanol present in the original sample. The method of distillation involves heating the samples to the boiling point of…

    analysis to determine the unknown alcohols used to produce the esters. Acetaminophen, a popular active ingredient in many over-the-counter drugs, is used as a pain reliever and a fever reducer. It is synthesized from the reaction between a carboxylic acid and an amine; thus, acetaminophen contains hydroxyl and amide functional groups.1 C6H7NO + C4H6O3 C8H9NO2 + C2H4O2 This reaction is commonly known as a condensation reaction. A condensation reaction is a chemical reaction where two reactants…

    aspirin Aspirin, also known as acetylsalicylic acid, is an aromatic compound containing both a carboxylic acid functional group and an ester functional group. Aspirin, being a monoprotic weak acid, is only slightly soluble in water and it can be prepared by reacting salicylic acid and acetic anhydride in the presence of an acid catalyst. 1.2: History of aspirin Aspirin was first produced about 110 years ago but the natural form, salicylic acid, found in plants (i.e. the willow and myrtle)…

    In this study, multiwalled carbon nanotubes@poly(p-phenylenediamine)-prussian blue (MWCNTs@PpPD-PB) nanocomposites were synthesized and used for the nonenzymatic electrochemical detection of hydrogen peroxide (H2O2). The PpPD layer also helps the MWCNTs to be dispersed in the water together with the PB formation and fixing on the surface of the MWCNTs. Moreover, PpPD, a conductive polymer, increases the electronic conductivity and stability of MWCNTs. By combining the selectivity and catalytic…

    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…

    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…

    moiety was also protected as its O-Boc enol carbonate (Figure X.X.X). Transient in situ O-silylation facilitated the preparation of bis-N-Boc nucleosides from unprotected sugars. This strategy allows the protection of nucleosides with a base-stable and acid-labile group suitable for the preparation of base-sensitive oligonucleotides as well as for further manipulation. However, the utility of this diBoc carbamate protection is yet to be explored in oligonucleotide…
