Exp D. Post Lab Questions

1. What is the purpose of the concentrated sulfuric acid in the first step? The purpose of using concentrated sulfuric acid is to activate the reaction of salicylic acid and acetic anhydride and produce the acetylsalicylic acid, which is aspirin. The sulfuric acid is used to protonate oxygen atom of a carbonyl group of salicylic acid.

2. What would happen if the sulfuric acid were left out? Removal of catalytic acid from the reaction would slow down or not proceed at all because the phenol group on salicylic acid is not strong nucleophile. And it requires an acid substrate to activate the reaction.

4. What is the equation for the decomposition reaction that can occur with aspirin?

6. A student performed the

    On the way from solar cell to the solar module, the output efficiency decreases. For example when a multi-crystalline PV solar cells of 17.8% efficiency is used, the resulting efficiency of a module is around 15.9 to 16.3%. This decrease in efficiency is mainly because of three distinct losses listed below. 1. Optical losses generated by material reflectance and absorption 2.…

    b. When measuring the resistance value with the Avo 8, possible reasons for varience include a parallax error (not looking at the reading from directly above the meter), a reading error due to less divisions when measuring resistance, or the device not being properly zeroed. When measuring current, there are also fewer division, parallax is still a potential issue, and finally, incorrect zeroing of the meter. Voltage has an additional error, the loading of the meter itself. Alongside this issue, there is also parallax, zero, and accuracy/divisions.…

    Objective Review: 1. Describe the purpose for using aseptic technique in collecting specimens Aseptic technique is used to prevent contamination of specimens by pathogenic organisms. The goal of maintaining asepsis is to not introduce any other organisms to the patient and prevent the spread of any organisms the patient may be carrying. Certain practices are used to help decrease this from occurring including cleaning, sanitizing, and disinfecting. Aseptic technique is an important process to prevent the spread of infection and diseases in the clinical setting (Hauswirth & Sherk).…

If you are unfamiliar with the concept of the root user, do a quick google search. It is always a good practice on any operating system to run your applications on a user level and leave the administrative tasks to the root user, and only on a per-need basis. Applications are meant to be run by users with non-administrative privileges.(Power December 4, 2010)…

    Pglo Lab Report

    Purpose: The overall goal of this lab was to perform a procedure on E. Coli which involved transferring genes that encoded for the green fluorescent protein into E. Coli to see if the transferred genes would make a difference on the growth and whether or not the bacteria would glow under UV light. Hypothesis: If the bacteria with the pGLO plasmid was grown on a plate containing LB and ampicillin then the bacteria will grow but not glow under UV light. If the bacteria with the pGLO plasmid was grown on a plate containing LB, ampicillin, and arabinose then it will be able to grow and glow under UV light. If the bacteria without pGLO plasmid was grown on a plate containing LB and ampicillin then it will not be able to grow or glow under UV light.…

    The lab instructor issued out a test tube labeled with letter ‘I’, which consisted of two unknown bacteria, Gram-positive or Gram-negative that were streaked from a pure culture. Sterile techniques were followed while performing precise instructions as stated in the referenced Laboratory Manual. Example 1: The first procedure performed was done by isolating a pure culture from the mixture onto a solid Trypticase soy agar (TSA) media. Sterile technique was done by flaming the loop until it turned red to ensure that there were no current bacteria on the loop avoiding contamination followed by rapidly flaming the neck of the test tube to prevent the entry and contamination of unwanted microbes.…

    Acetaminophen Synthesis Lab Report

    Introductions: The purpose of this experiment is to synthesize acetaminophen and esters in order to apply the process of retrosynthetic analysis to determine the unknown alcohols used to produce the esters. Acetaminophen, a popular active ingredient in many over-the-counter drugs, is used as a pain reliever and a fever reducer. It is synthesized from the reaction between a carboxylic acid and an amine; thus, acetaminophen contains hydroxyl and amide functional groups.1 C6H7NO + C4H6O3 C8H9NO2 + C2H4O2 This reaction is commonly known as a condensation reaction.…
