The subject of Chemistry contains overall 30 lectures and 30 laboratory practicals in Winter-term. Participation in the laboratory practicals is compulsory and the attendance will be recorded each time. In case of more than three absences the lab course will not be acknowledged. Participation in the lectures is also compulsory and the attendance will be checked regularly. Students having more than three uncertified missed lectures do not receive a signature in Chemistry, and they are not entitled to sit the end-of-term examination in December-January.

Any recent Chemistry textbooks of college or higher level can be used (e.g. Raymond Chang, Ken Goldsby: Chemistry, McGraw-Hill Inc., 11th edition, 2012). The use of Chemistry Laboratory Manual is prescribed because this Manual serves as the laboratory protocol, as well. The free electronic (pdf) 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 – 16:15 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, Manual and safety goggles (provided in the lab). In case of missed lab exercise(s) due to documented illness or serious family issue, the student has to take make up lab(s) the last week (Dec. 10 -14) of Winter-term 2018.

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 and set back the reagents to their original place. Before leaving the laboratory students have to get a valid signature of attendance from a supervisor in the Manual.

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)            Supervisors will randomly check preparedness of the students with a short written test in the lab three times during the term. The subject is the topic of the current lab. With these short tests the students can collect 3×5=15 points.

2)            Midterm Tests. During the term all students are obliged to perform two written tests (60 min./test), whose subject includes the topics of the laboratory exercises and the related lectures.

Test 1: Oct. 29, 7:00                     Chemical calculations (stoichiometry) (15 points)

Test 2: Nov. 26, 7:00                    pH calculations (15 points)

The tests cannot be later upgraded. Only those students who missed the midterm test(s) due to documented illness are obliged to write a make-up test(s) on December 09th at 16:30. The make-up test(s) topics include the subjects of the missed test(s). The results of any 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.

3)            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).

4)            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 17th 2019, January 7th, 14th, and 27th 2020 from 14:00 at Chemistry Lecture Hall. (Please, arrive 15 minutes earlier.)

The grade will be determined by the sum of points from the midterm-, and  lab tests, and examination (155 points overall) as follows:

Points Grade
0 – 76 unsatisfactory (1)
77 – 96 pass (2)
97 – 115 fair (3)
116 – 135 good (4)
136 – 155 excellent (5)

 

To help the study 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.
