CHEM 243 Modern Chemical Analysis
The theory of chemical equilibrium as it pertains to acid-base, metal-ligand, redox, and EDTA titrations. Topics such as experimental design, sampling, calibration strategies, standardization, and the optimization and validation of experimental results will be covered. Statistical analysis of data will also be included. This class is meant to aid students in developing both a sound knowledge of experimental protocols (i.e. How many samples do we need to collect? How do we extract our analyte from the matrix? How much sample must be extracted in order to obtain a measurable result? How do we measure what's present? and in the critical evaluation of experimental results (How much confidence do we have that our results are representative of the system under study?). Three hours classroom and four hours of laboratory per week. Prerequisite: 132 or 141.
