The students created and presented posters that explained and highlighted the most important topics discussed during the study of the scientific content throughout the semester. These posters were evaluated with the assistance of faculty members and teaching assistants from the department and other departments. Subsequently, the department professors awarded certificates of appreciation and trophies to the best posters. 

The goal of this activity was to provide students with a comprehensive understanding of various analytical chemistry techniques, with a focus on titration methods and factors affecting solubility and complex formation. By exploring the effects of common ions, temperature, and pH on solubility, students learn the fundamental principles governing chemical equilibria in solutions and the role of the solubility product constant (Ksp). 

The activity also covered the solubility product constant to predict precipitation formation, equipping students with the knowledge needed to analyze and accurately interpret solubility data. Additionally, the activity emphasized the development of practical skills in various titration techniques, including the Fajan’s method, Volhard’s method, bromometric titration, iodometric and iodimetric titrations, and Karl Fischer titration. 

These methods are essential for determining various samples such as metal ions, phenols, sulfa drugs, and water content in samples. By participating in these titration experiments, students gain hands-on experience and analytical proficiency, preparing them for advanced studies and professional work in the fields of pharmaceutical and analytical chemistry. 

The students in each lab were divided into 3-4 groups by the teaching assistant or the assistant lecturer in charge, with each group presenting part of the curriculum in the form of a poster. It was emphasized that sources must be added to the posters, and each group was evaluated by the faculty members. The students’ activity and efficiency were evident during the presentation.During the presentation, the students demonstrated both activity and competence.
