Sharpie permanent markers contain n-propanol (C3H8O) n-butanol (C4H10O), and Diacetone alcohol (C6H12O2). These markers are generally used on hard, non-porous surfaces, because instead of damaging the surface they form a surface layer that can be removed easily by solvents such as acetone (C3H6O), xylene (C8H10), or toluene (C7H8). Acetone (strong chemical used in nail polish remover) is a strong and very effective against permanent markers. It can also remove paint and melt certain surfaces.…

Project 3 Identification and Synthesis of an Unknown Ionic Compound Mitchell Morgan CEM-161-007 Josh Ward 28th October 2015 Abstract The chief objective of this experiment was to identify the unknown compound. The following tests were conducted to eventually establish the identity of the compounded: qualitative solubility tests, anion and cation tests, flame test, and the formation of a precipitate. The physical properties of the unknown ionic compound found that it has no smell and was…

The dehydration of Cyclohexanol requires going through an acid-catalyzed elimination of water for the synthesis of cyclohexane from cyclohexanol. To get cyclohexane from cyclohexanol you must remove the cycloalkane with fractional distillation, drying with anhydrous sodium sulfate, and analyzed by GC data and the bromine test. The reaction we are trying to accomplish going from cyclohexanol to cyclohexene is a secondary alcohol going through an E1 reaction. This is the unimolecular…

fertilizers, rodenticides, and food preservatives.Turbidity is caused by sediment or other pollutants and causes the water to appear murky or cloudy. (2008) The pH can be changed by some of the rocks in the water, such as limestone which neutralizes the acid in the water. (Oram, no date) “Nitrates are forms of nitrogen and is found in several different forms in terrestrial and aquatic ecosystems”. Nitrates in the water are caused by wastewater treatment plants, runoff from fertilized yards,…

is controlled by the hypothalamus and pituitary gland by a buffering system. A buffer solution is used to maintain the pH at a safe acidity. “A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid” (Boundless, 2010) Equation 1 – Generic Buffer Equation HA (aq) + H2O (l) --> H3O+(aq) + A-(aq) Note that equation 1 is reversible, and all equations that are reversible have to be at a state of.equilibrium.…

Explain the results you obtained using a piece of muscle and a piece of potato?. Both the test tubes will show decomposition of hydrogen peroxide because both potato and uncooked ham have catalase enzymes. 5. What effect did acetic acid (vinegar) have on the reaction? Why? The catalase enzyme works best at pH 7 but it can perform well between 6.8 to 7.5. A 0.1 M Vinegar has a pH approximately 3. 2cm of them should have reduced the pH from 7 interfering with the breakdown of hydrogen…

Results showed that the basic amino acids for sea bass fillets were glutamic acid, aspartic acid and lysine. The amount of methionine, tyrosine and histidine were lower than the other amino acids. Similar to the data obtained by Ozden and Erkan (2008). Fish are quite rich in lysine (Ozden and Erkan, 2008) and other reported that the main amino acids in sea bass were aspartic acid, glutamic acid and lysine also, The changes in amino acid contents in fish muscle were affected by spawning…

Hot packs and cold packs are a useful item when it comes to treating injuries. Inside a pack is salt and a certain amount of water. When you break the pack, the salt mixes with the water causing a reaction that either increases or decreases the temperature. When these salts dissolve in the water it creates a reaction that is either endothermic or exothermic. Endothermic is the absorption of heat. This is when the pack gets hotter. Exothermic is the release of heat. This is when the pack gets…

experiment was to measure how much the pH changes when an individual adds a certain amount of acid or base to water, biological buffers, and other biological solutions. It is vital to study the changes in pH because a slight change in pH in an organism’s body can disrupt metabolism activities and even cause death. To accomplish the purpose of the experiment, an individual will add certain amounts of acid or base to water, biological buffers, or other biological solutions. pH is a measure to…
