    A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the

    Titration of a Weak Acid Introduction: We will be using the LoggerPro and LabPro in order to help us determine our data. The purpose of this experiment is to follow the changes of pH during the titration of an acid and a base in order to determine the of the weak acid‚ . is a constant for a given acid at a given temperature. In this experiment we determined the Ka using two different methods: 1) the measurement of the pH of a solution containing a known concentration of a weak acid‚ and 2) measurement

    William Perez Cell Biology 2440 Lab on protein Myosin Proteins are chains of amino acids that perform the most important functions in living organism. Every protein will contain an amino group‚ carboxyl group‚ a different R group and an alpha carbon with two hydrogens. There are nine types of functions proteins can have‚ enzymes‚ motor‚ receptor‚ structural‚ storage‚ transport‚ signaling‚ and special purpose proteins(antibodies). There are four levels of protein structure‚ primary‚ secondary

    It was hypothesized that if the animal was larger‚ then it would have larger hemoglobin. It was thought that larger mammals would need more oxygen-rich hemoglobin to support healthy function. This lab did not support this hypothesis. The results in table 1 displayed that the hemoglobin of all mammalian samples traveled about the same distance. This trend can be seen in graph 1 as the mammalian hemoglobin samples migrated the same distance. Because the proteins traveled around the same distance it

    In acid solution‚ MnO4- ion undergoes reduction to Mn2+ this is the equation: 8H+(aq) + Mno4-(aq) + 5e-  Mn2+(aq) + 4H2O Since the KMnO4 – ion is violet and the Mn2+ ion is nearly colorless‚ the end point titrations using KMnO4 as the titrant can be taken as the first pink color that appears in the solution (and stays without disappearing). The titration which involves the oxidation of Fe2+ ion to Fe3+ by permanganate ion‚ is carried out in sulfuric acid to prevent air-oxidation of Fe2+

    Piumbroeck Chem 214 Acid-Base Titration‚ Determination of Carbonate and Bicarbonate in a water sample Introduction The purpose of this lab is to determine the concentration of two bases‚ carbonate and bicarbonate‚ by using a potentiometric titration. We can determine the concentration of the bases in the reactions ( H+ +CO3- < ==> HCO3- and H+ + HCO3- < ==> H2CO3-) by the way the pH of the solution changes. The way the pH changes when a strong acid is added can be used to

At the start of the experiment‚ we prepared standards of benzoic acid solutions that contained 2‚4‚6‚8‚ and 10 mg/L in 0.10M HCl‚ our group prepared the 6 and 6 mg/L standards for all the groups within the laboratory. In one of the 100mL volumetric flask it contained 6 mg/L benzoic acid + 10 mL HCl‚ then diluted to the mark on the flask with DI Water. In the other 100mL volumetric flask it contained 8 mg/L benzoic acid + 10 mL HCl‚ then diluted to the mark on the flask with DI water. Standards

    by the body will form a chemical called uric acid. Uric acid mostly can be found in foods and drinks like dried been and pears. Normally‚ most of the uric acid dissolves in blood and move from blood to the kidneys. High level uric acid kidney or blood caused some bad effect such as leukemia‚ hyperuricemic and lymphoma. Therefore‚ the electrochemical method (graphene oxide modified glassy carbon electrode method) are introduced to detect the uric acid in human urine sample. Previously‚ the electrode
