Analytical chemistry I is a foundational course for undergraduates majored in chemistry. This course includes classical chemical quantitative analysis and basic instrumental analysis. The major content includes tools and operations in analytical chemistry, acid-base equilibria and titrations, complexometric reactions and titrations, gravimetric analysis and precipitation equilibria, precipitation reactions and titrations, redox and potentiometric titrations, introduction to instrumental analysis, electrode potential and potentiometry, voltammetry and polarography, electrochemical sensors and (electro) chemiluminescence, introduction to spectroscopy, UV-visible spectroscopy, IR and Raman spectroscopy. This course is intended to provide students with an understanding of basic principles and instrumentations of analytical chemistry that are important in chemistry, biology, material, medical, and engineering.
