Solutions. Chemical reactions. Stoichiometric calculations. Reaction speed. Chemical equilibrium (Le Chatelier principle. Chemical equilibrium constant). Heterogeneous chemical equilibrium. Solubility product. Gravimetric analysis, pH. Acid and base equilibria, buffers. Volumetric analysis (theoretical principles, conditions of volumetric analysis, classification of volumetric methods, equivalent point, neutralization). Acid-base titrations and EDTA titrations. Basic principles of electrochemistry, electrodes and potentiometry, redox titrations. Fundamentals of spectrophotometry, UV-visible spectrophotometry (introduction, Bouguer – Lambert – Beer law, UV-visible spectrophotometers, applications of spectrophotometry in chemical analysis), atomic spectroscopy. Method of known addition and internal standard.

Laboratory Exercises

• Introduction (Solution normality – equivalent weight).
• Determination of food moisture (gravimetric analysis).
• Neutralization titrations: Oximetry (preparation – titration of a standard solution).
• Alkalimetry.
• Determination of natural product juice acidity.
• Determination of alkaline sodium compounds (NaOH, NaHCO₃, Na₂CO₃).
• Manganiometry (redox titrations).
• Silver measurement (sediment formation titration Mohr method).·
• Titration of compound complex formation (water hardness).
• Spectrophotometry.

Educational Goals

The course aims to achieve the following learning outcomes for students:

• The understanding and consolidation of modern Analytical Chemistry methods applied in the field of Food Science and Technology. Both classical methods of chemical analysis and an introduction to instrumental methods of analysis are included.
• The correct physical understanding of the principles of analytical chemistry.
• The application of classical quantitative chemical analysis methods in practice.
• The understanding and consolidation of the basic operating principles of each analysis method.
• The study of the possibilities presented by each of them, as well as the development of selection criteria for each method as well as the possibility of combining these methods.
• The ability to process and evaluate the measurements as well as the presentation of the results.

General Skills

• Search, analysis and synthesis of data and information, using the necessary technologies.
• Promotion of free, creative and inductive thinking.
• Work in an interdisciplinary environment.
• Autonomous work.
• Teamwork.
• Decision making.
• Generating new research ideas.

Teaching Methods

Face to face:

• Lectures (theory and exercises) in the classroom.
• Laboratory exercises.

Use of ICT means

• Lectures with PowerPoint slides using PC and projector.
• Notes in electronic format.
• Use of videos and online applications.
• Post course material and communicate with students on the Moodle online platform.

Teaching Organization

Students Evaluation

Evaluation methods:

• Mandatory attendance at (at least) 80% of the laboratory exercises.
• Mandatory written work for each laboratory exercise (20% of the final grade).
• Written final exams in the theoretical part of the course with problem solving (60% of the final grade).
• Final written exams in the laboratory part of the course with multiple choice, short development and problem solving questions (40% of the final grade).
• Optional written assignments in the laboratory exercises (20% of the grade of the laboratory part of the course if submitted).

The evaluation criteria are presented and analyzed to the students at the beginning of the semester.
