Annotation -
The seminar to the subject Analytical chemistry I (MC230P35) is devoted to basic calculations in analytical chemistry according to the syllabus. The content of the seminar facilitates to the students the calculations in the course MC230C11: Analytical Chemistry for Clinical and Toxicological Analysis - Lab and standard analytical practice.

Learning outcomes
A student after completing the seminar...
... correctly writes the required formula of a chemical compound and, conversely, names the compound based on the formula.
... on the basis of the formula, calculates the content of the relevant element or group in the compound or, on the contrary, proposes the summary formula of the chemical substance from the contents of the individual elements.
... calculates the mass and volume fraction, mass and volume percentages, or the mass concentration of the component in the sample, taking into account the described dilution, the density of liquid solutions, or pressures of gases and their mixtures.
... calculates the substance (molar) concentration of the component in the sample, taking into account the described dilution, densities of liquid solutions, or pressures of gases and their mixtures.
... converts information about the content of the component in the sample (e.g. in percentages, in units of ppm, ppb, etc.) to substance (molar) concentration or vice versa as specified.
... calculates the correct method of diluting (including dissolving the weight and volume of solvent) a substance or its solution with a pure solvent or other solution to obtain a solution with the desired properties.
... writes down the equation of a chemical reaction (or fills in its products), calculates the equation and uses the obtained stoichiometry to calculate the required result; in the case of an oxidation-reduction process, he / she also writes down and correctly calculates the equations of the ongoing oxidation and reduction.
... calculates the concentration / content of a substance or ion in a solution based on data on its solubility, or solubility product; the calculation will also include the effect of the ionic strength of the solution and other present ions.
... sketch the titration curve of a simple precipitation titration.
... calculates the contents / concentration of substances or ions in the solution, including taking into account the stability constants of the resulting complexes, or limited solubility.
... sketches the titration curve of a simple complex-forming titration, or distribution diagram.
... calculates the pH of solutions: strong acids; strong bases; weak acids; weak bases; their salts; buffers.
... calculates the buffering capacity of the solution.
... plots the titration curve of any combination for acid-base titrations.
... sketch a distribution diagram of polyhydric acid or base.
... calculates the value of the distribution ratio from the weights of the vaporization residuals or the known extraction yield.
... calculates the yield of a single extraction based on knowledge of the distribution ratio.
... calculates the number of necessary extractions to obtain the specified amount of a certain substance.
... obtains the desired result by any combination of the above calculation procedures, either in the described or in the reverse direction of the calculation.

Requirements to the exam -
Participation is not necessary, it is important to master the seminar. During the semester, it is possible to write three (announced one week before) midterm tests, with a maximum score of 20. Those who achieve at least 90% of the maximum total of each of the three midterm tests receive a credit. In addition, at the end of the semester (in the credit week and during the exam period), the summary tests with the maximum number of points 30 are written. The summary tests are published and applied via SIS, the maximum number of attempts is three. The sum of the points from the best of the midterm tests and the comprehensive test must reach at least 30 points to get the credit.
