Module: Inorganic chemistry (objectives)

1) Knowledge and understanding: at the end of the course which also includes the organic chemistry module, and following the individual study commitment, the student has an adequate knowledge of the chemical concepts preparatory to the correct understanding of the subsequent TAE programs that involve basic and more advanced concepts of general and inorganic chemistry.

2) Ability to apply knowledge and understanding: At the end of the course and following the individual study commitment, the student achieves an adequate preparation which, together with other, more specific knowledge that he/she will acquire later on, will allow them to move and operate in areas of innovative applications, including international ones. The student will be able to use the fundamentals of chemistry for specific applications in the agri-food and oenological fields, also for the development of eco-sustainable methods and productions. By way of example, the student will be able to orient himself in the choice of different products, making this choice also on the basis of the knowledge acquired.

3) Independent judgment: At the end of the course and following the individual study commitment, the student is able to critically interpret any data relating to production processes in the food and wine sector. The student is able to evaluate possible qualitative aspects related to the use of preservatives and additives. The autonomy of judgment will be mainly oriented towards an assessment of the quality of the food product.

4) Communication skills: At the end of the course and following the commitment of individual study, the student is able to communicate and share knowledge related to the discipline to interlocutors of the same level and non-specialists. The student is able to interact constructively, in relation to the studied discipline, with other people of similar cultural background. These skills are also developed thanks to individual commitment, written tests and oral tests, which represent the moment of synthesis of the study path.

5) Learning skills: At the end of the course and following the individual study commitment, the graduate student has developed a certain degree of critical approach. And he/she now knows how to find all the useful information to contextualize a problem, through the use of the tools offered by scientific literature.
