inhibit the corrosion rate of metal alloys but cost effectiveness, toxicity, processibility and other factors limit the applications1. The need for new, eco-friendly and cost effective corrosion inhibitors have led to research in the field of polymer chemistry. Discussion The performance of a polymeric corrosion inhibitor is a function of its size and number of functional anchoring groups1. The anchoring groups allow the polymer to adsorb to the metal surface and assist in corrosion mitigation.…

Sulfur: Research Paper by Brian Zhang 805 If you ever happened to unnerve a grumpy skunk, then you would have understood the severe atrocity of its scent firsthand. What you probably didn't realize, however, concerns the fact that sulfur holds much blame for the nasty occurrence. In fact, this mother of repulsive odors earns its spot on the periodic table as one of the world's 118 chemical elements, or substances that contain only one type of atom. Much like any other non-metal, it does…

Triton X-100 at 40 ⁰C for 10 min, followed by soaking in sodium hydroxide (NaOH) solution at varies concentrations (1, 2 4, 6 and 8%) at 100 ⁰C for 60 min. For enzymatic retting, the fiber was treated with chelating agent, enthylenediamine-tetraacetic acid, then immersed in 0.85% solution of Triton X-100 at 40 ⁰C for 10 min, followed by adding of pectinase at different concentrations (0.25, 0.5, 1.0 and 3%) at 50 ⁰C for an hour. They concluded all treatment resulted in reduction of lignin and…

Summary: Put on any necessary personal safety equipment, and one person from each team should collaborate with people from other teams to create the NaOH solution. The other team members should focus on setting up the buret by rising it with distilled water as well as building the titration apparatus and preparing the HCl solution. In order to prepare the NaOH solution, first take some solid NaOH and measure its mass. Then get a 250 mL volumetric flask and fill it about halfway with distilled…

aids in digestion and helps to relieve digestive problems as well. • Stimulates hair growth: Mustard oil contains high levels of beta carotene and Vitamin A, iron, fatty acids, calcium and magnesium that stimulate the growth of hair and keep it healthy. • Improves heart health: Mustard oil is rich in omega-3 and omega-6 fatty acids which lower the cholesterol levels and promote the good cholesterol which in turn ensure that the cardiovascular health is maintained. Consuming mustard oil helps to…

DETERMINATION OF STOMACH ACID NEUTRALIZATION USING ANTACIDS Authors: Alexxis Harris Constance Doty Brandon Hokenson Gavin Hunt Melissa Munoz Affiliation: Department of Chemistry, University of Central Florida Abstract The purpose of this experiment is to identify which antacid is the best at neutralizing stomach acid. Antacids are commonly used self-prescribed medications. The stomach produces hydrochloric acid, which has a…

When dealing with pharmaceuticals you have to deal with mixing substances together, knowing how much to put in every dosage, acids and bases, matter, chemical and physical properties, and etc. Pharmaceuticals are made of elements that are apart of the periodic table. That happens when combining two or more elements together causing a chemicals reaction. Also in chemistry is a law called the Law of Conservation of Matter which is used to determine chemical composition in compounds and chemical…

This week's reflection assignment consists of one video. It features Mr. Larry Potterfield (founder, and CEO of Midway USA) as the presenter. The video is titled "Gunsmithing: How to properly polish the metal parts on a Remington 700". Mr. Potterfield begins his first video by stating the objective, polishing metal parts. In his hands, he holds the barrel of a Remington 700 series rifle. It appears as if the rifle has definitely seen some cleaner days, in my opinion. This is a skill every…

solution of the unknown compound and water. To further identify properties, five reactions were carried out with the unknown compound and the known compound and the results were compared. These five reactions included mixing the unknown with an acid, a base, two with salts, and one that was known to create a precipitate. The same reactions were carried out with the known. Respectively, the known/unknown were reacted with HCl, NaOH, NaCl, CaCO3, and HNO3 and AgNO3. With the results lining up…

is a method used to determine the mass or concentration of a substance by measuring a change in mass. To determine the concentration of the sulfate, the precipitation of Barium sulfate is done first by adding the sulfate solution with hydrochloric acid, then heating while stirring it. Next is the washing and filtration of the Barium Sulfate precipitate, using a vacuum pump and a crucible. Lastly, is the drying and weighing of the precipitate by heating the crucible in the oven and cooling it in…
