Folic acid

reduces pain and inflammation by limiting certain hormones. The drug is taken orally, usually in the form of a pill, and is absorbed into the bloodstream once it dissolves. Both human saliva and human stomach acid aid in dissolving the pill. Human saliva has a pH of about 6, and stomach acid has a pH of approximately 2. The purpose of this investigation is to discover whether the pH of a solution will affect the time needed to dissolve the ibuprofen. Hypothesis If the pH of a liquid is…

Acid, below-normal pH, causes many problems in our world today—from drinks to teeth, from pollution of industry to natural disasters. Acid is a chemical substance that can subdue alkalis, can dissolve specific metals and can turn them into salt, such as calcium, turns red on blue litmus paper, is corrosive or sour-tasting when it comes to liquid, generates pain in wounds, and turns colorless when placed in phenolphthalein which is used as a basic to acid indicator ("Definition of acid in…

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…

5 : Uses of lecithin. Use Concentration (%) Aerosol inhalation 0.1 IM injection 0.3–2.3 Oral suspensions 0.25–10.0 8 Description Lecithins vary greatly in their physical form, from viscous semiliquids to powders, depending upon the free fatty acid content. They may also vary in color from brown to light yellow, depending upon whether they are bleached or unbleached or on the degree of purity. When they are exposed to air, rapid oxidation occurs, also resulting in a dark yellow or brown…

Therefore, the structural and optical characterization of prepared samples was carried out by using these instruments. 3.2 Synthesis of ZnO Nanostructures ZnO nanoparticles were prepared by using the following reagents : Starch solution Zinc nitrate hexahydrate {Zn〖(NO_3)〗_2 .6 H_2 O} Sodium hydroxide { NaOH) Freshly prepared ammonia solution. In order to prepare 0.01M of ZnO nanoparticles, the following steps were followed: The 0.01 M of Sodium hydroxide { NaOH}…

of the Concentration of Acid in Gastric Juice Introduction Titration is a method where a solution of known concentration is used to find the concentration of an unknown solution. A standard solution is a solution of precisely known concentration. The aim of this experiment was to go over the use of pipettes, burettes, titrations and also to reinforce the concept of molarity. In this experiment, a titration was carried out using a standard solution of hydrochloric acid to establish the…

constant variable is the acid which is in the flask. When the solid acid dissolves to form ions, 1 mole of H+ ions are produced for every mole of acid being used. Molarity is used to calculate moles per liter of solution. The most dangerous part of this lab is the risk of getting…

place within cells without being used up in the process. According to the website, www.ducksters.com, “enzymes are special types of proteins. Like all proteins, enzymes are made from strings of amino acids. The function of the enzyme is determined by the sequence of amino acids, types of amino acids, and the shape of the string.” Along with this we need to know about a peroxidase; “A peroxidase is one of a number of enzymes that act as catalysts to allow a variety of biological processes to take…

species to increase, but also has several negative effects that could cause species to become extinct. Ocean acidification occurs as the ocean absorbs carbon dioxide from the air which then causes the ocean 's pH level to decrease. As the ocean 's acid levels increase, it can affect marine life by helping organisms who make energy by combining sunlight and carbon dioxide, but hurts the chemical communication, impact, and growth of many organisms by increasing the pH. Overall, the increase in…

slowly. In order to speed up the process, hydrochloric acid (H+) was used as a catalyst. A catalyst is a substance that can speed up a reaction by lowering the activation energy of the reaction. It does this by changing the mechanism of the reaction and providing more energetically favorable elementary steps that would otherwise not exist without its presence. In addition, a catalyst does not get used up in the reaction. In this case, hydrochloric acid reappears in the products of the reaction…
