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…

“DEVELOPMENT AND VALIDATION OF STABILITY INDICATING METHOD FOR SIMULTANEOUS ESTIMATION OF CEFTRIAXONE AND TAZOBACTAM INJECTION USING RP-UPLC METHOD” 2.1 OBJECTIVE To develop and Validate Stability Indicating Method for simultaneous estimation of Ceftriaxone and Tazobactam in their combined dosage form by RP-UPLC method in various stress condition like, alkaline, acidic, oxidative, thermal and photo degradation. 2.4 METHODOLOGY 2.4.1 Chromatographic Condition Column Separation was achieved by…
in the liquid phase according to the radical mechanism produced by MEC as the intermediate and acetic acid as the final product. Mice and acetic acid (0.2: 1.0 mass ratio) are obtained by non-oxidizing liquid phase oxidation at 1800C and 53 bars with remixing. Continuous oxidation under the flow conditions of components at 1500C, 65 bar and the stay time of 2-7 minutes constitute MEK and acetic acid by 3: 1 mass. This process has a slight economic advantage over the removal of 2-butanol. But the…

1. Abstract In this study, reverse micellar extraction of asparaginase model system was carried out using CTAB/Iso-octane/hexanol/butanol system to optimize the forward and back extraction efficiency. By using Taguchi’s orthogonal array (OA), maximum forward extraction efficiency of 55.0%, 61.0% and 54% was achieved with an aqueous phase pH of 11.0, 150mM CTAB/Iso-octane and 0.1 M NaCl, respectively. Similarly, Taguchi’s orthogonal array (OA) was applied to optimize the pH of stripping phase,…
