Learning Outcomes of the Curricular Unit:
The Curricular unit has as main objective the acquisition of the fundamental principles of analytical chemistry and the adaptation of this knowledge to the laboratory practice indispensable to the future professional. The skills to be developed are based on the knowledge of the aspects inherent to the quantitative chemical analysis, which will serve for the understanding and execution of the activities carried out in the laboratory. The objectives to be achieved are: O1. Identify the scope and application of analytical chemistry O2. Know the steps of the chemical analysis and plan an analytical procedure O3. Acquire the theoretical bases inherent to a volumetric analysis O4. Understand the basics of acid-base, oxidation-reduction, complexation and precipitation volumetries O5. Develop laboratory skills to perform volumetric analysis and to interpret the results obtained O6. Transfer the knowledge of analytical chemistry to laboratory practice in a real work context

Demonstration of the Syllabus Coherence with the Curricular Unit's Objectives:
The syllabus (CP) of the Analytical Chemistry Curricular Unit provides students with the acquisition of scientific, technical and interpersonal skills that allow them to develop their future professional laboratory activity in this area. CP1 Introduction to Analytical Chemistry and CP2. Analytical procedure aim to achieve objectives O1 and O2. The CP 3. General aspects of the volumetric analysis serve to achieve the O3 objectives. The CP involving the different types of volumetry (CP4-7) were designed to achieve the O4-O6 objectives.
Teaching Methodologies (Including Evaluation):
M1: Exposition and debate of relevant theoretical concepts in the classroom. Didactic material will be made available on the e-learning platform M2: Orientation of students' autonomous study in the practical component. In practical classes, students will be asked to solve a series of questions with an objective answer and numerical problems. M3: Active participation of the student in the teaching-learning process through the execution of a set of laboratory works. Assessment: the acquisition of knowledge of the theoretical component is validated by carrying out two written tests (with a weighting coefficient of 30% in the final grade of the course). The evaluation of the practical component (with a weighting coefficient of 70% in the final grade of the course) will be based on laboratory performance, on the quality of the reports delivered (60%) and on two written tests (20% each). The final classification will only be awarded when both components are approved.
Demonstration of the Coherence between the Teaching Methodologies and the Learning Outcomes:
The constant interaction betweenledcturer and the student in class will allow the student to adapt to the proposed objectives. In the theoretical classes, the general principles inherent to chemical analysis are exposed, ranging from the preparation and manipulation of solutions to the fundamental operations for the execution of an analytical procedure. Then, the different types of equilibria and their application in traditional quantitative analysis are studied. The topics covered in the theoretical classes will be consolidated through the resolution of application exercises in practical classes. In laboratory classes the student will become familiar with the practice of quantitative chemical analysis by performing a series of laboratory works using classic methods of analysis based on different types of chemical equilibrium. The methodologies (M) defined are articulated with the objectives (O) proposed: M1: Exposition and debate of relevant theoretical concepts in the classroom - Aims to achieve O1-O6. M2: Orientation of students' autonomous study in the practical component - Aims to achieve O3-6. M3: Active participation of the student in the teaching-learning process through the execution of a set of laboratory works - Aims to achieve O5 and O6.
