CHEM 2303: ANALYTICAL CHEMISTRY II LECTURE 1 – INTRODUCTION‚ SAMPLE PREPARATION AND SPECTROPHOTOMETRY WHY STUDY ANALYTICAL CHEMISTRY? To gain a knowledge of the methods and strategies that have been developed to investigate the nature of the chemistry around and within us. To answer the age old questions: What is it? What is it made of? How does it work? We must learn the principles of chemical analysis and the array of strategies that have been developed to analyze chemistry. HOW DO WE ANALYZE

Ms. Wilson Chem‚ Blk 10 31 October 2012 Atomic Emission Spectra Lab Atomic spectroscopy is the determination of elemental composition by its electromagnetic or mass spectrum. An arrangement of all wavelengths of electromagnetic radiation is called the spectrum; the plural being spectra. As light passes through a prism‚ the frequencies of light emitted by an element separate into separate lines to give the atomic emission spectrum of the element. There are two spectrums in the lab: the incandescent

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 : Iron in Breakfast Cereal by Atomic Absorption Spectroscopy OBJECTIVES : 1) To determine the actual iron content of different brands of cereals 2) To compare the experimental results with the values listed on the manufacturer’s labels. INTRODUCTION : Iron is one of the important minerals that is required for our bodies to function properly. Most of the iron in our body is found in the blood such as haemoglobin‚ approximately 60 -70% of the human body’s iron is found

The natural plant exudate gum tragacanth is obtained from the stem of the bush like plant “goat’s-horn”‚ Astragalus species. Gum tragacanth has been used commercially for well over 2000 years and is currently widely used as a thickener and emulsifier in emulsion systems in different pharmaceutical‚ food‚ cosmetic and diverse industrial uses. In addition‚ it is on the list of stabilizers that are permitted by Food and Agriculture Organization/ World Health Organization that could be used during the

Experiment 2 Quantification of Proteins in Solution by Spectrophotometer Lab bench# 1 Introduction: Absorption spectroscopy is a common method for finding the concentration of proteins or protein complexes in a solution. Proteins absorb light at specific wavelengths and can be defined by the equation A = log (Io/I). This equation states that an absorbance at a specific wavelength‚ A is equal to the log of the ratio of incident light intensity (Io)‚ to transmitted light intensity (I). A
