Introduction to Chemical Analysis and Electrochemical Techniques

Full transcript

Lecture one begins with chemical analysis: quantitation, identification, detection, and separation. We classify analysis by method, classical or modern, and by purpose, quantitative or qualitative, then by sample and analyte amount, followed by the analytical process sequence. Next, we explore errors in experimental work: sample, analyte, matrix, standard, and blank. Errors are gross, determinate, or indeterminate, each needing specific solutions, while accuracy and precision are measured through absolute error, percentage error, and standard deviation. Finally, electrochemical techniques split into interfacial and bulk methods like potentiometry and conductometry. Lecture two covers key terms—electrodes, electrolytes, and cells—explains why electrochemical techniques matter, and introduces electrochemical cell types, including galvanic cells that convert chemical energy into electricity.
