Learning outcomes The main objective of this curricular unit (CU) is to prepare the students for an efficient accomplishment of the main unit operations used in Chemistry.
To this end, it is intended that students acquire the experimental skills to perform these operations effectively and safely, as well as the theoretical knowledge necessary for a correct interpretation of the obtained results.
Thus, at the end of this course, the student should be able to:
- Identify safety rules and procedures in chemistry laboratories;
- Recogn
ize the physical, chemical and toxicity characteristics of reagents and solvents;
- Identify the objectives of the proposed experiments and the experimental methods to carry them out;
- Select glassware and laboratory equipment according to the application;
- Properly handle reagents, material and basic equipment in the laboratory;
- Observe, measure, record and organize experimental data;
- Interpret the observations and experimental results obtained.
Syllabus 1. Introduction to the laboratory:
- Basic Rules of Safety and Conduct in a Chemistry Lab

Teaching Methodologies and Assessment Criteria Theoretical-practical classes, with the support of audiovisual media and carrying out application exercises.
- Laboratory classes, where students perform laboratory work using a provided procedure guide. During these laboratory classes, students will have to write down the observations in the laboratory notebook.
At the end, they make a report, in group, that will allow the consolidation of the knowledge acquired during the performance of the experimental work.
Language Portuguese. Tutorial support is available in English.
