General Chemistry - Laboratory

Laboratory classes are designed to familiarize the student with the principles of good laboratory practice, with the concepts of accuracy and precision of determinations, with classical methods of quantitative analysis based on acid-base reactions and complexation reactions. Acquired manual skills are necessary in any laboratory work.

After completing the course of this subject, the student should know the basics of classical quantitative analysis and demonstrate the ability to plan, perform and describe an experiment as well as respond to the obtained result.

During the laboratory classes, students perform exercises that allow them to acquire the basic skills required in each laboratory:

• measuring liquids, heating solutions, sludge precipitation, sludge roasting, titration technique, keeping a laboratory diary, presenting the result of the analysis

• calibration of flasks and pipettes,

• weighing reference substances on an analytical balance,

• performance of quantitative determinations:

Preparation of the solution approx. 0.2 mol/L HCl and setting its concentration to a Na2CO3 weight against the reference buffer. Determination of NaOH.

Preparation of 0.05 mol / L EDTA, setting its concentration to ZnO. Titration of the Ca2 + and Mg2 + ion mixture

1.Analytical procedures available in the laboratory and sent via email at the beginning of the class.

2. Materials presented by teachers during a discussion of the basics of classical chemical analysis methods and good laboratory practice at the beginning of the class.

Knowledge: student will know:

• basics of analytical chemistry in the field of quantitative analysis methods and the basics of inorganic chemistry,

• basic principles of occupational health and safety sufficient to work in a chemical laboratory and will have ordered knowledge of the principles and ethical standards related to scientific and didactic activities.

Skills: The student will be able to:

• apply the learned chemistry laws in the analysis of selected chemical problems,

• carry out quantitative analysis of inorganic substances,

• plan and perform basic research, experiments and observations, and critically evaluate the results,

• comment on topics related to chemical problems. Is convinced of the importance of behaving in a professional manner, observes the principles of professional ethics.

The student will be aware of the scope of his knowledge and skills and understand the need to improve professional and personal competences.

Social competences: student

• will be able to work in a team and be aware of the responsibility for jointly performed tasks and the belief in the importance of behaving in a professional manner and the need to comply with the principles of professional ethics.

• understand the need to improve professional and personal competences.

The final grade consists of:

- assessment of theoretical knowledge (colloquium written after the end of laboratory classes); open questions; 50% of points must be obtained
