  • The Pros And Cons Of Purrified Water

    Water purified by means of reverse osmosis, and other demineralizing procedures is not healthy for human consumption, and the distribution of this water is unethical because of these health issues. It turns out that the purification of water removes vital nutrients and minerals, not just the toxins in the water. Water purified by reverse osmosis is in fact water in its purest form, almost 100% H2O, but that does not make it healthy for the human body, which requires minerals which can only be sufficiently absorbed by water that has not been purified. “When we drink purified water, we are consuming a pure chemical substance, H2O. Pure chemical substances of any kind are not found in nature collected together, but instead are always mixed with other substances. Because of its extreme purity, purified water absorbs carbon dioxide from the air, which makes it acidic and even more aggressive at dissolving the alkaline substances it comes in contact with.” (Purified Water and its…

  • Recrystallization Essay

    This technique involves several steps, selecting an ideal solvent, dissolving the compound in a minimum amount of boiling hot solvent, filtering insoluble impurities while the solution is hot; crystallizing the purified compound, and isolate the pure compound by vacuum filtration . The unknown used in the experiment was #4, which were white crystals. In order to determine the ideal solvent we prepared two test tubes. Test tube #1 containing 0.106g of unknown and 3mL of water, it was well…

  • Step 2-Synthesis Essay

    to urea and the liquid is then furthurly purified. Then, the second reactor receives the gas from the first reactor and recycles the solution. Conversion of carbon dioxide to urea is approximately 60% at a pressure of 50 bar (g). The solution is then purified in the same process as was used for the liquid from the first reactor. Step 2 - Purification The major impurities in the mixture at this stage are water from the urea production reaction and unconsumed reactants (ammonia,…

  • Acetanilide Pyridinium Tribromide

    was brought to the hood and 7.0g of pyridinium tribromide was added and then stirred for about 30 minutes with a watch glass as a cover. While stirring, 10% sodium bisulfite was added in 1ml increments until the orange/red color disappeared or was less intense. After, the solution was cooled in an ice water bath. Once crystals formed, the solution was filtered using a funnel. The product was then recrystallized from 95% ethanol and water. In order to do this, the amount of ethanol used was…

  • Water Purification And The Supercooling Process

    types of water, the history of water purification, and the supercooling process, one could find different types of articles and videos that explained everything very thoroughly. All of the authors and websites had given a much better idea of the topic of supercooling. To fully understand the supercooling one must understand different types of waters. The purpose for this paper is to understand the water types, the history of water purification, and the topic of supercooling. To accomplish this…

  • Isopentyl Acetate Synthesis Lab Report

    Introduction In this experiment, isopentyl acetate was prepared by the direct esterification of acetic acid with isopentyl alcohol, which is an equilibrium that results in a shift in favor of the product by using one of the starting materials in excess. An esterification reaction is when an acid is converted into an ester by combining with an alcohol and removing a water molecule. Esters are found in numerous natural products, including fruits, flowers, and spices. Carboxyllic esters contribute…

  • Columbiana Flood Assessment

    Elementary and High Schools, which centralize in the school district, were flooded, including the practice fields and playgrouds. The main agriculture here is cotton. Besides, the main industry is tourism. The Groundwater flow is from the west to the east, and the drinking water sources are all flooded. All surface water was flooded obviously. Even though some residences have private wells and others get water from the city, but all wells including city’s and private were flooded.…

  • Chitin Lab Report

    Chitin is the second most abundant natural polysaccharide consisting of β(1→ 4)-linked N-acetyl-D-glucosamine (GlcNAc) units in a linear form. Chitin is insoluble in water and mainly exists in two crystalline (α- and β-) forms. The α-chitin consists of sheets of tightly packed alternating parallel and antiparallel chains (1) and is abundant in the exoskeleton of arthropods, insects, fungi, and yeast cell walls. The chains are arranged in parallel orientation in β-chitin (2), which occurs less…

  • Thesis Statement About Salt

    Although, some seas may have greater concentration. For instance, the Dead Sea and the Great Salt Lake have a much higher salt concentration. First, the concentration level is raised to 25.8% NaCI after going through the condensers, which are heat transferring device that converts vapor into liquid. The reason for the conversion is to later be easily able to remove any impurities in the mixed water solution through the process of crystallization. Second, through the sun and wind’s energy, salt…
