1 Coordinating unit: ETSEIB - Barcelona School of Industrial Engineering Teaching unit: EQ - Department of Chemical Engineering Academic year: Degree: 2015 BACHELOR'S DEGREE IN CHEMICAL ENGINEERING (Syllabus 2010). (Teaching unit Compulsory) ECTS credits: 6 Teaching languages: Catalan, Spanish Teaching staff Coordinator: Others: FRANCISCO JAVIER GIMENEZ IZQUIERDO Gimenez Izquierdo, Francisco Javier Gibert Agullo, Oriol Degree competences to which the subject contributes Specific: 1. Capacity to acquire fundaments and methods of organic and inorganic chemical analysis and their application in an industrial environment. Teaching methodology The methodology consists on theoretic lessons where the teacher presents the learning objectives in relation to the contents of the subject. The contents are subsequently applied to solve practical problems. In these practical problems students are encouraged to actively participate. Real cases related to both industry and environment are also developed in order to learn choosing the adequate analytical techniques. The adequate material and tools for the learning process are available for the students. The Digital Campus is also a web tool that is being used in order to give the students different material of the subject and in addition it is a tool to improve the communication between teachers and students. Learning objectives of the subject The global objective of Analytical Chemistry is the students to learn the basic principles and applications (industrial and environmental) of the analytical chemistry, including classic and instrumental techniques. At the end of the lessons, the students should be capable to: 1) Describe the scientific basis and most important applications of classic and instrumental techniques in analytical chemistry. 2) Distinguish the chemical needed pre-treatment of a sample before using any analytical technique. 3) Determine the concentration of any analyt in a sample by using titrating techniques. 4) Select the adequate analytical technique for the determination of the concentration of a solute in a sample. 5) Transform the signal of any instrumental technique in concentration units. 1 / 7
