Ateneo - UPO

Study of chemical equilibria in solution and volumetric determinations. Practical experiences in laboratory.

Available material, Skoog-Leary - Chimica Analitica Strumentale - EDISES

The students should be able to understand and solve problems about chemical equilibria in solution, knowing qualitative and quantitative chemistry procedures. Scope of the course is to enable students to perform the analytical methods of qualitative/quantitative analysis in the laboratory providing them with the fundamental concepts for good laboratory practice and promoting their autonomy.

None

In class lessons, laboratory experiences

The knowledge is evaluated by classroom exercises.
Students with physical disabilities, Learning Disabilities or Special Education Needs can request specific services and tools via the Staff Sviluppo e Coordinamento Carriere e Servizi alle Studentesse e agli Studenti, consulting the University webpage: https://www.uniupo.it/en/services/servicesstudents-physical-or-learning-disabilities.

Students with disabilities, learning disabilities or special education needs, once they have contacted the University Staff, can refer to the tutor in charge of the course to define the examination modalities, concerning academic aspects.

Written exam consisting of exercises on chemical equilibria in solution (acid-base, buffers, solubility product, complex formation, redox, competitive equilibria).
An example exam from a prevoius session and its solutions will be available on the Moodle platform. The written exam is followed by its discussion by the student, and a discussion on the laboratory reports.

Equilibria in solution (acid-base, complexes, precipitation, redox); activity coefficient; volumetric determinations (titration curves, indicator systems, important titrations).
Quantitative methods: method validation, representation of the results (average, standard deviation, confidence interval and Statistical hypothesis testing), critical level, LOD, LOQ, calibration curve, internal standard method, standard addition method, single addition method.
Laboratory
ectures: brief introduction to laboratory experiences.
Individual and/or group laboratory exercises include:
• titration of copper by complexometric route
• determination of copper and zinc in one of its most common alloys: comparison of the results obtained by determination in UV-Vis spectrophotometry and titration.
