Course abstract
The aim of the study course is to learn the most important laws of inorganic chemistry, knowledge of chemical elements, their compounds and properties, as well as to learn the methods of quantitative analysis of substances. In quantitative analysis, the theoretical foundations of titrimetric methods, as well as gravimetrical and spectrophotometry analysis methods are learned, and appropriate laboratory work is done. Students are introduced to the general physicochemical characteristics of food products. The acquisition of knowledge and skills is ensured by a range of teaching materials, exercises and laboratory works that demonstrate the important place of inorganic and analytical chemistry in the chosen specialty.
Learning outcomes and their assessment
After completing the course, students will have: Knowledge and critical understanding of the properties of inorganic substances, methods of determining the quantitative composition of chemical compounds, regularities of transformations and their practical importance in food technology (tests).
The skills to evaluate and choose the most suitable methods of analysis of food products and to carry out these analyses, as well as the knowledge base for learning future study courses, which includes the skills to think analytically and creatively use the regularities of chemistry in practice, both in the study process and in professional activities (laboratory work, independent work, discussion seminars). Competence - objectively evaluate new information about the use of chemical elements and compounds in the food industry, independently find and select it, as well as use it when solving questions related to the analysis of chemical compounds in practical work (independent work, discussion seminars, laboratory work protocols).
