Analytical chemistry as one of the four basic chemistries is an academic discipline, responsible for characterizing the composition of natural and artificial materials, both qualitatively (what is present) and quantitatively (how much is present). That is, analytical chemistry is the science of inventing and applying the concepts, principles and strategies for measuring the characteristics of chemical systems and species. It has been widely applied in many research fields including life science, material science, environmental science and energy. The teaching emphases and difficulties of this course focus on the four principles of titration analysis and the processing of errors and analytical data. Through the system study of analytical chemistry, it can make students deeply understand the theories of chemical analysis and possess basic experimental skills as well as accurately build the concept of "quantity". Furthermore, the course will train students to develop the capacities of preliminary selecting suitable analytical method, correctly judging and expressing the analytical results, and even solving practical problems in different cases and scientific problems. In conclusion, this course lays a solid foundation for learning subsequent professional courses.
