Chemistry Laboratory

Undefined

The contents of the laboratory matter are presented in laboratorial lessons, being then applied to the practical works done in the laboratory. The study material and practical work protocols will be available to students through the platform adopted by ISEC.

With this curricular unit it is intended that the students develop the skills, attitudes, behaviours, methodologies and the best practices, scientific reasoning and that they:
»Acquire the theoretical and practical foundations of Chemistry Laboratory and the classic Analytical and Quantitative Chemistry.
»Acquire the theoretical and practical foundations in volumetric acid-base, precipitation, complexation and acid-base.
»Acquire the skills of self-organization, communication and relational.
»Acquire technical skills in the domain of the chemist laboratory at the level of the basic safety and handling of chemicals in the laboratory, preparation and standardization of the solutions used in chemical analysis and quantitative treatment of samples for chemical analysis.
»Acquire technical skills in the use of conductometry, potentiometric and volumetric as specific analysis techniques.
»Acquire skills in the interpretation of results of analysis

1. Basic laboratory techniques: weight, volume. Containers for storage solutions and material packaging. Preparation of solutions.
2. Volumetric acid-base: Preparation and standardization of aqueous acids and bases solutions. Determination of the concentration of an ionic compound and an acid
3. Volumetric precipitation: Preparation and standardization of an aqueous solution of an ionic compound and determination of the ions.
4. Volumetric complexation: Preparation and standardization of an aqueous solution of a chelating agent and determination of the ions.
5. Volumetric oxidation-redution: Preparation and standardization of an aqueous solution of an ionic compound and an aqueous solution of iodine. 
6. Assays by gravimetric method: Methods and tools. Application.
7. Electroanalytical methods: Conductivity and potentiometric titrations.
