Coordination Complexes of Cobalt Advanced Inorganic Chemistry Lab 02/27/2015 Abstract When the transition metal‚ cobalt‚ forms a complex involving a nitrate ion‚ the ligand has the ability to coordinate via N or O. The ability of the nitrate to attach via the N or O gives rise to the term‚ linkage isomers and can affect the functionality of the complex with other molecules. To explore structural differences between complexes‚ pentaaminechlorocobalt (III) chloride‚ pentaaminenitritocobalt (III)

Determining the Absorbance Maximum Wavelength and Molar Extinction Coefficient to Find the Molarity of the Unknown DCPIP Background Information: A spectrophotometer is an instrument used to help determine the absorption spectrum of chemicals. It does this by reading the absorbance of the chemical at different wavelengths. All chemicals absorb light in their own distinct way. This distinction helps to identify unknown chemicals. The absorption of light within a chemical is also very important because

Mass Determination of Ca‚ Fe and Zn in a multivitamin using Atomic Absorbance Spectroscopy (AAS) and X-Ray Fluorescence Spectroscopy (XRF) ABSTRACT: The purpose of this project was to determine the amount of calcium‚ iron and zinc present in an over the counter multivitamin. This mass was determined using atomic absorption spectroscopy (AAS) and X-ray fluorescence spectroscopy (XRF). For both analytical techniques‚ the method of standard additions was used to compensate for matrix effects.

purpose of this experiment is to determine the maximum absorbance of fast green‚ and the chlorophylls‚ also in the case of fast green create a concentration curve to determine an unknown substance. Each test will use the spectrophotometer. Spectroscopy is the study of light. A spectrophotometer is a machine used to determine the absorbance of light at any given wavelength. It does this by using a source of white light through a prism‚ which gives multiple wavelengths that can be individually

Arene Molybdenum lab Introduction: Organometallic chemistry is the study of chemical compounds that contain carbon atoms bound to a metal atom. Organometallic compounds can contain main group elements‚ or more metallic elements such as zinc or carbon. These compounds tend to have carbon atoms bound to the metal center by σ-bonds. Alternatively‚ transition metals can be involved in the compound‚ which leads to a variety of interesting and diverse chemical characteristics. For example‚ a promising
