Annotation -
The aim of the subject is to provide the students with firm and sufficiently wide theoretical and methodological fundamentals for pursuing (in a rational way) chemical analysis of inorganic and organic substances. The teaching is focused on the explanation of theoretical aspects of instrumental methods. In practical training individual approach of students to solving analytical problems is required.

Learning outcomes

The subject Analytical Chemistry builds on the knowledge and skills acquired in the subjects: General and Inorganic Chemistry and Organic Chemistry I.

After completing the subject, students will be able to use the following terms in the correct context towards the analytical evaluation of inorganic and organic substances: group, selective and specific proof reactions for inorganic cations and anions; use of the solubility of group reaction products for separation; proof of organic compounds including elemental analysis and proof of functional groups; use of knowledge of solubility and acid-base properties of organic substances for proof of functional groups; volumetric analysis using various chemical principles, method of determining the equivalence point, standardization of volumetric solutions and calculation of content determination using direct, indirect and back titration.

Learning outcomes:

Based on the acquired knowledge and skills, students will:

describe the general procedure for proof of cations and list group reagents for proof of cations including the principle of proof reactions;

describe the general procedure for anion proofs and list the group reagents for anion proofs, describe the principles and evaluation of proof reactions;

describe the general procedure for the analysis of organic substances, including the difference between inorganic and organic qualitative analysis, describe the procedure for elemental analysis, solubility test and proof of functional groups of organic substances;

describe the general procedure for titration with visual indication of the equivalence point, list the three basic types of titrations with regard to the speed and conditions of the chemical reaction, explain the procedure for standardizing volumetric solutions and propose the principle of titration for determining the content of a simple inorganic substance, calculate the content of the substance being determined
