I. Abstract The purpose of this practical was to measure the amount of a chemical substance present in a sample. Primarily‚ the aim of Experiment 1 was to measure the absorption spectrum of a particular coloured substance (in this case Bromophenol Blue and Methyl Orange) at varying wavelengths of light. The goal of this experiment was to measure the given amounts of a given chemical substance that was present in a given sample of Methyl Orange and in blood. We measured the optical density at wavelengths

Red Bull and Sugar Free Red Bull NMR Post Lab Report Abstract Viewed as one of the most significant tools in analytical chemistry‚ the Nuclear Magnetic Resonance (NMR) is a spectroscopy tool often used by chemists to determine the molecular profile – quality and quantity of the major components - of any given organic substance. Operating on basis of spectroscopy (study of the interaction between matter and radiated energy - Harris)‚ the NMR can be either a one (1H NMR) or two (1H/13C NMR) dimensional

Epoxidation Reactions Lab Report 2 Abstract An oxygen atom is transferred from a peroxy acid to the carbon=carbon double bond thus forming an epoxide. Scheme 1. Oxone Epoxidation. Scheme 2. mCPBA Epoxidation. The percent yield for the Oxone epoxidation reaction was 65% yield and the mCPBA epoxidation reaction was 70% yield. Oxone is the greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic

Emission Spectroscopy The purpose of this lab was to see that when elements are heated‚ they may enter and excited state. We proved this by doing a flame test. During Part A‚ we used a spectroscope where all of the colors are arranged for you; whereas in Part B‚ we could see and make the colors ourselves and get a more accurate reading of the flames. We had specific elements we were told to put on the wire loop‚ and when we did that we saw different color flames come out of the Bunsen burner. That

Individual Discussion Spectroscopy Dry Lab Lab Section M5 - Group 6 January 24‚ 2015 Discussion In this laboratory assignment‚ the spectroscopy data and molecular formula were given for 3 unknowns. An effort was made to conclusively identify these unknown samples using only the spectroscopy data‚ specifically 1H-NMR‚ 13C-NMR‚ and IR spectroscopy. Although mass spectrometry was given for the samples as well‚ its use was suggested only for confirmation‚ not identification‚ of the unknowns

Lab #4 Emission Spectroscopy and Flame Test Date of Lab: 10/24/13 OBJECTIVE To observe a continuous spectrum‚ emission spectrum‚ and an absorption spectrum‚ and be able to distinguish among the three. To be able to identify metal ions by doing a flame test and looking at a spectrum. At the same time increasing the ability to use and understanding of lab equipment‚ in this case‚ a spectroscope. To be able to calculate the frequency and energy of certain frequencies of light. PROCEDURE

Experiment H: Identification of an Unknown Organic Compound The objective of this lab was straightforward. We were given an unknown compound and we were to perform an IR spectroscopy and as well as NMR spectroscopy. With the IR spectroscopy‚ I was able to name the functional groups I have on my compound and further confirmed my assumptions by looking at the NMR spectroscopy after. The unknown number I was given was number 203. The molecular weight of the compound was 121. From the molecular weight
