Teaching Pattern

Methodology Lectures: The fundamental chemistry of aqueous solution, the basic principles of titrimetric methods and instrumental techniques (e.g. luminescence, UV-Vis spectrophotometry, IR, electrochemical methods), statistical analysis of experimental data and their use in chemical analyses will be introduced in lectures. Tutorials: Tutorial questions will be used to help students gain a better understanding on the lecture materials. For example, common questions involving qualitative (e.g. titration) and quantitative analyses (e.g. concentration and weight percent of analytes) will be given to students for learning purposes. Practical classes (virtual lab.): Students will develop their practical skills and learn to apply different analytical techniques in laboratories.
