The subject of Chemistry contains overall 30 lectures and 30 laboratory practicals in Winter-term. Wearing face mask is obligatory during the lectures and the practicals because of the COVID pandemic. Participation in the laboratory practicals is compulsory and the attendance will be recorded each time.

Any recent Chemistry textbooks of college or higher level can be used (e.g. Raymond Chang, Ken Goldsby: Chemistry, McGraw-Hill Inc., 11^th edition, 2012). The use of Chemistry Laboratory Manual is prescribed because this Manual serves as the laboratory protocol, as well. The free electronic (pdf and mp4) version of the lecture slides can be downloaded from the Intranet after username/password login.

Participation in the Laboratory Training

The duration of each practical is 2 × 45 min., and they will be held without breaks:

Monday, 8:15 – 9:45 for groups 5, 6

Monday, 10:15 – 11:45 for groups 3, 4

Monday, 12:15 – 13:45 for groups 11, 12

                     Monday, 14:15 – 15:45 for groups 7, 8

                     Tuesday, 10:15 – 11:45 for groups 1, 2

                     Tuesday, 15:15 – 16:45 for groups 9, 10

at the Student Laboratory (ground floor, room No. 8) of the Department. The individual workplace of students in the Laboratory is optional but it should be kept during both Terms. Participation in laboratory exercises will be not allowed without a lab coat, face mask, Manual and safety goggles (the latter is provided in the lab). In case of missed lab exercise(s), the student has to take make up lab(s) at the last week (Dec. 09 -11) of Winter-term 2020.

Evaluation description

Preparation for Lab Exercises

The goal of laboratory practices is to perform experiments and demonstrations in the laboratory, which will provide empirical evidence for the factual knowledge obtained from the theoretical lectures. A thorough theoretical preparedness is needed for a successful practical laboratory work. Before the chemistry lab class it is important to review the relevant chapters of the lecture(s)/textbook(s) of chemistry,  and to study the extensions found in the Manual. Supervisors might check the preparedness and work of the students during the lab exercises. In case of unsatisfactory preparedness the given practical will not be accepted, therefore it should be repeated in the same week or as a make up lab.

Each laboratory experiment should be done individually (except for demo-, and group-experiments) and should be started right after the introduction. The observations and experimental data should be instantly documented after the given experiment on the odd pages of the Manual. However, writing the reaction equations and calculations in the Manual, before (at home) the given lab practical is highly recommended.

At the end of the practical, the students have to clean the used lab-tools, disinfect the surface of the table and set back the reagents to their original place. Before leaving the laboratory Manuals will be collected. The checked Manuals can be taken by the group leaders, in two days from the student’s lab.

For the make-up lab last week one should fill (copy) and learn the missed lab(s) in the Manual and (s)he will be asked few short, theoretical questions from the missed lab(s). If they are properly answered then one can get the valid signature(s) for the missed lab(s).

Requirements

1)            Midterm Test. During the term all students are obliged to perform one written test (45 min), whose subject includes the topics of the laboratory exercises and the related lectures.

Test: Nov. 23-24, in lab time     Chemical calculations (stoichiometry) and pH calculations (20 points)

The test cannot be later upgraded. Only those students who missed the midterm test due to documented illness are obliged to write a make-up test on the last week of the term. The result of the test will be announced within 3 working days from the writing date. Smartphones, graphic calculators, netbooks, tablets and other text storage electronic devices are not allowed to use during the tests/exams. Cheating, plagiarism or use the above mentioned devices are not tolerated (0 point), and the incidence will be promtly reported to Department of Student Affairs.

2)            Titrations. The submitted results of two titrations (i.e. analytical determination of mass-concentrations of NaOH and FeSO₄) in exercises No. 10 – 11 will be evaluated with 0 – 5 points/titration (0 – 10 points overall).

3)            End-of-term Examination. The Winter-term has to be closed with a 120 min. written examination with 100 points, which includes all subjects of lectures and laboratory exercises (General-, and Inorganic Chemistry) except calculations. To pass Chemistry, minimum 50 points of the exam must be achieved despite of the overall points.

The Chemistry exams will be held on: December 21^st 2020, January 5^th, 12^th, and 26^th 2021 from 14:00 in different lecture halls. (Please, arrive 15 minutes earlier.)

The grade will be determined by the sum of points from the midterm test, titrations and examination (130 points overall) as follows:

To help the study online consultations will be organized according to the agreement with the students. The consultation is not a simple repetition of the lectures but it can give help to understand the difficult parts of the subject and guidelines in preparation for the midterm tests. The exact date of these sessions will be announced in time.

If the teaching will be changed to full online system, the new requirements will be announced later.
