Course content
|
Content of lectures: 1. Physico-chemical spects of water (general properties: odour, colour, temperature, absorption of electromagnetic radiation, solubility; thermodynamics and kinetics of reactions in water; pH, acids, bases, carbonate system; complexation reactions; sorption reactions; oxidation - reduction reactions). 2. Inorganic substances in natural waters. 3. Organic substances in natural waters. 4. Influence of biological and physico-chemical processes on water quality. 5. Pollution in water ecosystems. Origin, function, categorisation of soils. Chemical properties of soils. Soil solution, soil gas. Acid-base equilibria in the soil solution. Redox equilibria in the soil solution. Adsorption processes in soils. Content of practices: Determination of: orthophosphates (spectrophotometrically), nitrates (ISE), nitrites (Bendschneider-Robinson method), sulfates (conductometrically), lead and other metals in soil leachates of ciggarette butts (AAS). Evaluation of possible methods for a selected organic pollutant in water or soil sample and limits of the methods.

Learning outcomes
|
The aim of the course in the part of aquatic chemistry is to present information about composition of aquatic systems, chemical processes influencing composition and properties of the systems and the analytical methods used in aquatic chemistry. In the part of soil chemistry introduction into origin, categorization and chemical characteristics of soils is presented. The course also contains a part dealing with sustainability of aquatic and soil ecosystems
Students learn to apply the principles of physical chemistry on aquatic and soil system. They master all fundamental chemical processes in fresh as well as ocean waters and in soils. Students become competent in performing classical methods of fresh waters analysis, they are also introduced into some modern instrumental methods - in cooperation with the Institute of Hydrobiology (Academy of Science)

Prerequisites
|
Advanced knowledge of inorganic chemistry and physical chemistry is required. Practical skills in chemical laboratory are needed.
|
|
Assessment methods and criteria
|
Combined exam, Development of laboratory protocols
To pass successfully the course, the student must complete the practical laboratory part (including preparation of the final report) and succeed in the oral exam, where the student not only demonstrates mastery of the new subject matter but also understanding of the context and connection with the knowledge covered in the previous study of chemical subjects. The absence of basic knowledge from the previous study of chemical subjects is a reason for not passing the exam.
