Course detail

Laboratory Classes in Laboratory Technics I

FCH-BCT_ACH1_PAcad. year: 2017/2018

Laboratory code and safety measures, basic laboratory work - weighing, measuring volumes of liquids, filtration, heating, annealing, cooling, dehydrating, distillation, crystallization, decantation, sublimation, extraction, determination of physical variables - refracting index, melting point, density, pH. Simple tasks - fraction crystallization, preparation of the solutions with accurate concentrations, distillation of salt acid, separation of a mixture by precipitation, gas preparation.

Planned learning activities and teaching methods

The course uses teaching methods in form of Laboratory exercise - 4 teaching hours per week. The e-learning system (LMS Moodle) is available to teachers and students.

Assesment methods and criteria linked to learning outcomes

The laboratory notebook (control of preparation), report sheets, tests, style of the work, course-unit credit test.
Evaluation of the test: excellent [100%-90%], very good [89%-80%], good [79%-70%], satisfactory [69%-60%], sufficient [59%-50%], failed [49%-0%]
The average from the evalution of the report sheets, of the tests, of the final test and style of the work is the final evalution of the course.
