LABORATORY FOR GENERAL AND INORGANIC CHEMISTRY
Learning outcomes of the course unit
The Course of Laboratory of General and Inorganic Chemistry has the aim to provide the students with the fundamental concept and to show the principal experimental techniques which are necessary for the study of Chemistry. In particular, two fundamental aspects will be highlighted: the numeric/stoichiometric aspect (calculations, use of formulae, use of software for the numeric data treatment) and the experimental aspect (participation to lab activities, use of the instruments in the chemical laboratory).
Comprehension skills: the Course will stimulate the study of Chemistry through three approaches:
- Methodological aspect (use of books and handouts, interaction with the teacher)
- Contents aspect (capacity in acquiring and usage of proper language and terms)
- Critical aspect (critical evaluation of own skills, interaction with other students)

Assessment methods and criteria
The student will be asked to demonstrate to have acquired:
- fundamental concepts
- skills in presenting the concepts using an adequate approach and consistent with this field of study
- capacity to connect the different concepts, demonstrating the ability to find individually the solutions to problems
- capacity to use textbooks, handouts and data on websites, and the capacity to critically evaluate this material
- knowledge in the fundamental techniques in the chemical laboratory
- capacity to describe in a written form (reports) their lab activities, and to integrate it with the theoretical concepts.
Final exam (written and oral) and report on the lab activities.
Part of the didactic material is available online for the students.
The teacher is available upon request for discussions and clarifications
about specific topics.
