A basic kinetic study of a chemical reaction often involves conducting the reaction at varying concentrations of reactants. In this way, you can determine the order of the reaction in each species, and determine a rate law expression. Once you select a reaction to examine, you must decide how to follow the reaction by measuring some parameter that changes regularly as time passes, such as temperature, pH, pressure, conductance, or absorbance of light. In this experiment we will use color change to derive the initial rates of the reaction. Before coming to lab you should read in your text the section on ...

Abstract
This experiment sort to find an accurate and most viable method that would be used in laboratories to the measurement of iron concentration in aqueous samples. The methodologies that were identified for further analysis included; colorimetric assay (molecular spectroscopy), flame atomic absorption spectroscopy, redox titration (volumetric) and cation exchange chromatography (EMA technique). These methods were analyzed of their advantages and later subjected to a validation test. In the process, a wide range of CRMs were used alongside six other samples that contained unknown iron concentration.
The experiment was thus, geared towards providing answers to statements like; the necessity of quantification of ...
