Laboratory manual is Dr. P. Scheiber, Dr. P. Nemes, Dr. T.R. Varga, Dr. Z. Vincze, and Dr. M.V. Pilipecz: Veterinary and Food Chemistry Laboratory Manual. Its use is prescribed; this manual serves as the laboratory protocol, as well. It can be received in the first week of the semester.
The laboratory exercises (2×45 min.) will be held without breaks for groups of:
7, 8 on Tuesday, 8:15 – 9:45
5, 6 on Tuesday, 14:15 – 15:45
3, 4 on Thursday, 8:15 – 9:45
1, 2 on Thursday, 10:15 – 11:45
9, 10 on Friday, 12:15 – 13:45
in Student Laboratory (Hallgatói Labor) of Chemistry Department (No. 8 on the ground floor in bldg. C).
Work in the Laboratory
1) Participation in each laboratory practical is compulsory and attendance will be recorded each time. Students who are unable to take the laboratory exercise(s) are obliged to give a satisfactory oral review of the subject(s) missed during their excused absence (make-up lab). Students who missed more than three labs, have to re-take the entire Veterinary and Food Chemistry course (with a new, unfilled Lab Manual) from February 2023.*
For the make-up lab (Exercise 13) one should fill (copy and learn) all the missed lab(s) in the Manual and (s)he will be asked a few short questions from the missed lab. If they are properly answered then one can get the valid signature(s) for the missed lab(s). Note: the exam is not allowed with a missed lab exercise(s).
2) A thorough theoretical preparation is required for a successful laboratory work! Therefore, a precise study of the related section of the laboratory manual and the thematically relevant chapters of the lecture before each laboratory exercise is a must. The preparedness of students can be checked at any time during the lab course and an unsatisfactory result will be considered as a missed lab exercise.
3) Wearing an apron (lab coat) and safety goggles are compulsory in the laboratory. At the first exercise, every student has to choose a permanent place at one of the lab desks. The laboratory experiments should be done individually (except group experiments). The observations, experimental data, and answers to the questions should be documented instantly in the Manual in the course of the laboratory exercises. However, it is highly advisable to write the reaction equations in the Manual before the given lab (at home). The right-hand pages of the Manual are left for that purpose. At the end of the exercise, the students have to clean the glass vessels and other tools and set back the reagents’ flasks to their place. Before leaving the laboratory students have to get a valid signature in the Manual from the supervisor.
4) To help the students’ work consultations can be organized. Dates of the consultations will be announced later, as agreed with the students. The consultation is not a simple repetition of the given subject but it can assist to its better understanding.
* Since it has financial consequence therefore, please contact with Mr Péter Lessi at Department of Student Affairs.
1) Midterm Test
A midterm test (45 min.) should be written in the spring-term on
Date: 5th week of April (April 26 – 28) during the lab
Topic: Chemistry of functional groups. Lecture notes will be asked also! (20 points)
Students who missed the midterm test due to illness (the medical certificate must be shown to Dr. M. V. Pilipecz within 7 days after recovery) will have one chance to write a make-up test on May 17, at 16:00. Further possibilities for the retake will be not given. The results of tests will be known to the students in 3 days from the writing date. Smartphones, graphic calculators, netbooks, tablets, and other text storage electronic devices are not allowed to use during tests/exams. Cheating, plagiarism, or use of the above-me devices are not tolerated (0 points), and the incidence will be promptly reported to the Department of Student Affairs. The written test is evaluated on a 0–20 point scale and these points will be added to the final exam’s points.
At the end of the spring term, the students have to write an end-of-term examination, which comprises all subjects of lectures and laboratory exercises of the spring term. The duration of the exam is 120 minutes and it is evaluated on a 100 point grading system. The first part of the exam contains 10 short, fundamental questions. In case of less than 5 correct answers, the result of the exam is unsatisfactory, independently of the other parts of the exam. More information about the exam will be given in the lectures. In the exam, there are no calculation exercises therefore only the use of an approved periodic table and ballpoint pen (with blue- or black ink) are allowed. Cheating or plagiarism in any form is not tolerated (0 points), and the incidence will be promptly reported to the Department of Student Affairs.
The final grade of the terms will be determined by the sum of points from the midterm test and the Veterinary and Food Chemistry exam (20 + 100 = 120 points = 100 %), as follows:
0 – 59 (0 – 49 %) unsatisfactory (1)
60 – 74 (50 – 62 %) pass (2)
75 – 89 (63 – 74 %) fair (3)
90 – 104 (75 – 87 %) good (4)
105 – 120 (88 – 100 %) excellent (5)
The Veterinary and Food Chemistry exams will be held on
May 24th May 31st June 14th June 21st
from 14:00 at Chemistry Lecture Hall. Please, be there 10 minutes before the exam at 13:50.
