Objetivos

The aim is for the student to acquire theoretical and practical knowledge of chemistry, which will support the preparation of specialized technical reports with clear, concise, and comprehensive information. This course also aims to enable the future professional laboratory technician in Chemical and Biological Laboratory to perform experimental work with an understanding of the scientific foundations that underpin it. Therefore, the curriculum deepens knowledge in chemistry at the level of major chemical equilibria, with exemplification through laboratory work.

Resultados de aprendizagem e competências

The aim is for students to acquire skills that enable them to access the job market as Laboratory Technicians, more specifically, in the area of simple chemical analyses, without resorting to instrumental methods.
