The course aims to stimulate in the student an attitude of attention towards the chemical phenomenon and to provide the minimum knowledge necessary to operate safely in a laboratory. In fact, in the first part of the course some topics of interest in laboratory practice will be developed, which usually cannot receive due attention in the other theoretical chemistry classes of the degree course. Space was given to the use of equipment and the main laboratory operations, such as classical and instrumental analytical techniques. Through a series of practical exercises, students will be taught to conduct simple experiments with the most common techniques used in a chemical laboratory and to analyze and interpret the results. Each student will be given the protocol of the exercise. The discussion of the experiment will be reported in the laboratory notebook, which will be corrected by the teacher at the end of each exercise to evaluate correct learning. Frontal and laboratory lessons are provided.

The course is divided into theoretical lessons and practical experiences.

It is advisable to take the General Chemistry exam.

In relation to the discipline, the student must show:

D1 Knowledge and understanding

The student will have to demonstrate the possession of a solid knowledge of the fundamentals of general chemistry related to the concept of mole, concentration, unit of measurement of concentrations, solutions, pH and solubility. You will have to show an understanding of the concepts and theory of basic chemistry with particular reference to equilibria in solution.

D2 Ability to apply knowledge and understanding

The student must demonstrate the ability to use, theoretically and practically, the knowledge acquired during the general chemistry course and during the lectures of the Laboratory 1 course (for a total of 28 hours) in all laboratory activities, showing the ability to make connections between the different topics and apply this knowledge to process the data and solve the questions.These skills will be tested during the course with the drafting of the reports relating to each exercise, to be included in the laboratory notebook.

During the laboratory activities (for a total of 28 hours per shift) the teacher will be supported by the laboratory tutor and by a teacher with a supplementary contract.

D3 Autonomy of judgment

The student will have to demonstrate that he is able to critically examine and argue the information contained in the protocol in order to correctly complete the laboratory exercise All this will allow him to develop the aptitude for problem solving that will be verified, both through the drafting of the report , relating to the exercise, in the laboratory notebook, which through targeted application-type questions in the oral exam.

D4 Communication skills

The student must demonstrate the ability to communicate the knowledge acquired to their colleagues and teachers using the specific language of the discipline. These skills will be tested during the oral exam.

D5 Learning skills

The student must show the possession of the learning ability, useful for the continuous deepening of the knowledge of basic chemistry, correctly using the study material provided by the teacher, the recommended textbooks and the in-depth material that can be obtained independently.

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

Teaching

Classroom lectures and practical exercises in the laboratory.

Attendance

Students are obliged to attend at least 2/3 of the lessons and to fill in the laboratory activity carried out with the relative calculations and comments in the laboratory notebook at the end of each exercise.

Course books

The teaching material will be provided by the teacher during the course and can be found, together with other support activities, within the Moodle platform blended.uniurb.it

Assessment

Written exam with a total of 6 exercises and open questions on different topics of the whole program. There is a maximum time for the exam and a pre-printed with a space for the 6 answers. The evaluation is comprehensive and takes into account various aspects including the number of correct answers and their quality. Written exam with open questions.

Disability and Specific Learning Disorders (SLD)

Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.

To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.
