Course detail

Basics of Laboratory Technique

FCH-BC_ZLTAcad. year: 2018/2019

Theoretical knowledges of laboratory equipment which is necessary for practicePraktikum z anorganické chemie I a Praktikum z anorganické chemie II.
Laboratory safety, first aid and disposal of chemical wastes. Laboratory equipment, basic laboratory operations, such as working with glass, weighing, measuring volumes of liquids and gases, heating and cooling, annealing, dissolution and dilution, separation of components of heterogeneous mixtures (such as decantation, filtration), separating components of homogeneous mixtures (eg. crystallization, distillation), further separation and purification techniques (eg, drying, extraction, sublimation, recrystallization), measurement of physical quantities (melting point, refractive index, density, pH).

Learning outcomes of the course unit

Students will get basic knowledge of commonly used laboratory techniques and basic laboratory equipment. Useful knowledge from other courses (primarily chemical calculations) are highlighted.

Planned learning activities and teaching methods

The course uses teaching methods in form of Laboratory exercise - 1 teaching hour per week. The e-learning system (LMS Moodle) is available to teachers and students.

Assesment methods and criteria linked to learning outcomes

At least 50% in the written examination is required to achieve. Students have three independent attempts, all questions have the same difficulty and are therefore assessed the same number of points.

Course curriculum

Laboratory safety, first aid and disposal of chemical wastes. Globally Harmonized System (GHS). Color marking of gas cylinders.
Basic laboratory equipment (lab equipment, glass, porcelain).
Working with glass. Working with scales. Volume measuring of liquids and gases. Approximate measuring volumes of liquids. Working with dispenser and automatic pipette. Principles of work with a standard glass (graduated cylinders, volumetric flasks, pipettes, burettes). Working with automatic burette.
Heating and cooling. Direct heating, gas and alcohol burners. Electric heat source. Indirect heating (liquid, steam, air and other bath). Annealing. Cooling (coolant, cooling media).
Separation of components of heterogeneous mixtures (decantation, filtration).The methods of filtration. Separation of the components of homogenous mixtures (crystallization, distillation). Types of crystallization. Distillation (simple distillation, fractional distillation, rectification, steam distillation, distillation under reduced pressure).
Further separation and purification techniques (drying, extraction, sublimation and recrystallization). Measurement of physical quantities (melting point, refractive index, density, pH).

Aims

The aim of the course is to prepare students for work in the laboratory. In theory, students are introduced to basic laboratory equipment and basic laboratory techniques.

Specification of controlled education, way of implementation and compensation for absences

It is necessary to complete all the exercises. Due to illness is a possible replacement in the other study group.
Students elaborate final test on elearning in the end of the semester.
