Objectives

After this course it is expected that the student will know and understand the fundaments of general chemistry. The student should be able to recognize the atomic structure and chemical bonds, basic foundations of chemistry, with the aim of understanding the structure of matter and its transformations, as well as understand and to know how to implement qualitative and quantitative chemical analysis, distinguishing between the different chemical equilibrium. Understand the acid-base equilibrium, knowing how to use buffer solutions, titrations and acid-base volumetry. Although the essentially introductory character of this UC, it is intended that students acquire skills allowing them a better adaptation and understanding of problems involved in chemical processes in the subsequent UC.
Teaching Methods

The lectures will be addressed with an essentially qualitative study of the fundamentals of general chemistry, suitable for students of first year of university level. Whenever possible, resort to the method of rediscovery and the use of models which make the concepts more real. In theoretical-practical classes, practical examples should be solved by students through application of the concepts used in lectures and with the teacher’s aide.

Content Explanation

To achieve the scopes of this UC, the student learn the evolution of the concept of atom and molecules. The student interprets the geometries adopted by molecules in the light of different models. The student understands the concept of intermolecular and intramolecular bond and the influence of the different intermolecular forces in the physical state and in the properties of matter. Also in the syllabus, is presents the various types of chemical equilibrium in a way to provide to the student capabilities to develop qualitative and quantitative chemical analysis about the different equilibrium and apply the acquired concepts in practical problems.
Methodology Explanation

The teaching methodologies applied were developed to help learning new concepts. The student is encouraged to obtain self-learning in order to become more autonomous and independent.
