Experiment 5 Analysis of Analgesic Tablet by High Performance Liquid Chromatography Abstract An unknown sample‚ 529‚ was tested using high performance liquid chromatography to detect the concentrations of acetaminophen‚ aspirin‚ and caffeine respectively. There was found to be 4.03±0.144mg/100mL of acetaminophen‚ 11.5±0.185mg/100mL of aspirin‚ and 4.89±0.185mg/100mL of caffeine. Based on accepted values‚ the maximum daily amounts of each compound are 4000mg of acetaminophen

Determining the melting point is very significant in order to identify an unknown. In this experiment‚ measuring the melting point was done by using melting point apparatus. The melting point of the unknown sample #10 was 111.5˚C. There were two possible compounds which were dibenzoyl ethylene and o-Toluic acid because their melting points were 111.2˚C and 109.8˚C when each compound was mixed with the unknown. Therefore‚ the unknown #10 was dibenzoyl ethylene. Introduction The melting point is defined

tests indicated that the unknown #4 was Streptococcus pyogenes. All seven tests on the unknown matched S. pyogenes perfectly. The blood agar plate proved the unknown to be β hemolytic‚ meaning the unknown bacteria was capable of complete hemolysis. This test separated the unknown into the β Streptococcus group‚ narrowing the possible bacteria to S. aureus or S. pyogenes. The Catalase test was used to determine if the unknown could break down hydrogen peroxide. The unknown bacteria was unable to break

Chemistry 28 March 2013 Identify and Unknown Ionic Compound ILI#3 Abstract: In this laboratory investigation‚ 8 solutions were combined with each other and an unknown liquid #1 in order to identify the ionic compound in the unknown solution. The students performed an experiment in which the reactions between each substance were compared to the unknown solution #1’s reactions and the color of each solution was compared to help find the unknown #1. The unknown ionic compound was identified to be

In this experiment the methodology used by the group is to perform the tests for both the unknown and the cations (Ba+‚Sr2+‚Ca2+‚ Mg2+ and NH4+) using the known as a control for comparison and identification of the unknown used. The unknown used in this experiment by this group is unknown # 9. The result obtained from this experiment shows that the unknown contains Ca2+‚ Mg2+ and NH4+cations.The test made for Ca2+ both on the unknown and the control
