Acid-Base Titration Lab Report By Andjela Mandic 11/24/14 Period 1 Purpose: The purpose of this experiment was to find the molarity of a sodium hydroxide (NaOH) solution by titrating it with a Hydrochloric Acid (HCl) solution. Materials: Burets (50mL), Buret Stand, Buret Clamp, Graduated Cylinder (10mL), Erlenmeyer Flask (125mL), Index Card, Beakers (250mL), Safety Goggles, Aprons, 0.100M HCl (standard solution), NaOH (concentration unknown), Distilled Water, Indicator (bromothymol
compounds have special properties that make them to react differently than other molecules. The conjugated compound of dienes in aromatic rings give an extra stability to undergo addition reactions
Comparison with the Pyro detect system The Pyro Detect System is use according to the manufacture’s instruction as quantitative test with the exception that sample are not test at different dilutions. The Quantitative test is described by the procedures as method A. By using method A, a quantitative comparison of the samples with the standard endotoxin is possible. The stimulating agents are pipette out as 20 µl portion into 96-well plate under a horizontal flow bench. The spike and blank wells –the
Mixed Unknown Bacteria Lab Report Biology 2460-002 Jamuna Kadariya November 24, 2014 Unknown number: thirty-four I. Abstract There are many types of bacteria and they produce different enzymes. However, some bacteria can produce same enzymes. In order to identify the particular enzymes produce by each bacteria specific test needs to be done. Among various types of enzyme producing bacteria, gram- negative and gram-positive bacteria are given priority in our experiment. There are four main types
2013) The reaction processes at 10∼20MPa and 130∼160°C, when cobalt is used as the catalyst. The products ratio of n-butyraldehyde and isobutyraldehyde is 3. The reaction processes at 0.7-3MPa and 80-120°C, when rhodium is used as the catalyst. The products ratio of n-butyraldehyde and isobutyraldehyde of 8-16 can be achieved. The catalysts of nickel or copper in gaseous phase or nickel in liquid phase are used for hydrogenation. Second process is aldol condensation, in this reaction; two molecules
