This practical course, intended for 1st year ST students, introduces the core experimental techniques of analytical chemistry and thermodynamics. There are four interconnected lab sessions. each one is addressed
through teaching sequences that allow the assimilation of the intended concepts. Each unit
includes learning activities where these concepts are applied and ends with assessment tests.The practical course begins with the determination of the calorimetric capacity of a calorimeter (Ccal), followed by the determination of its specific heat capacity, introducing students to the quantification of heat exchange. Students then perform acid-base titrations of strong and weak acids using a strong base to master volumetric analysis, neutralization stoichiometry, and concentration determination. The course concludes with colorimetric redox titration, where students explore oxidation-reduction reactions, electron-transfer stoichiometry, and the use of self-indicating reagents.
By the end of this course, students will be able to:
- Use laboratory glassware (burets, pipettes) and digital temperature sensors appropriately.
- Perform stoichiometric calculations for neutralization and redox reactions.
- Apply energy-balance equations to experimental data.
- Interpret experimental indicators and thermal signatures to identify, quantify, and characterize unknown chemical species.
