CHEM2133 Inorganic Chemistry Laboratory I Fall 2009 Section Tuesday 1:00 ‐ 4:00 PM Coordinator: Dr. Vladimir Zaitsev Office: 61‐F Contact no.: 3‐2725 E‐mail: email@example.com TA: Prem Kaewkunsri Office: 108‐SR1 Contact no.: 3‐2742 E‐mail: firstname.lastname@example.org There is no textbook. Materials will be provided. You are responsible for reading and knowing thoroughly the contents of these handouts. My expectations: Pre‐lab preparedness: laboratory instructions for each synthesis will be provided. You MUST read and understand the topic of forthcoming work prior to the lab session. I expect that all students will be working in the lab diligently, accurately and vigilantly, not posing any risk to other students and personnel in the lab or department. Slacking and bad attitude is not encouraged and will not be tolerated. Attendance is a necessary condition for success in this class. All experiments should be conducted and respective reports are written. PROCEDURE Section will meet in room 23‐F at the assigned time of 1:00‐4:00 PM. Anyone arriving 10 minutes late or more or miss the pre‐lab lecture will NOT be allowed to perform the experiment on that day. NO MAKE‐UP LAB. You must read the experiment handout and familiarize yourself with the procedures before the beginning of the class. You should sign in and put on your lab coat prior to enter the lab. At this time there will be a short lecture and an occasional quiz. When this is done you should put on your lab goggles and carry out the experiment, following ALL the procedures and safety rules.
After finishing the experiment, you MUST clean up your area, have your TA inspect the area and sign out. Lab reports must be turned in within seven days after the experiment is done. Lab coat, safety goggles, notebook and calculator are necessary prior to enter the lab. Place your bags in front to avoid accidents. No open‐toed shoes, shorts, food or drink in the lab. It is important to sign‐in and sign‐out. The experiment of the day must be finished 15 minutes before 4:00 PM (‐10 points on lab report). Safety issues: This course is experimental chemistry class that requires laboratory bench top work with both solid and liquid chemicals and their solutions. These include crystalline and powdery materials, some of which represent toxic substances, as well as strong acids and bases. All laboratory chemicals are considered to be hazardous materials. Therefore, constant and extreme caution as well as common sense should be exercised all the time during lab sessions. All generated wastes should be appropriately segregated in specialized containers and then disposed accordingly. SAFETY FIRST! Any willful disregard of the safety rules or other disobedience may result in grade loss, dismissal from the class, or a recommendation of suspension from school. GRADING You will perform seven experiments during the semester. Your final score will be based on your scientific reports and quizzes. The lowest score of a lab report and a quiz will be dropped. The total will be 800 points as explained below: 7 lab reports@ 100 points each
5 quizzes @ 50 points each
A grade of F will be automatically assigned to a student who missed two or more section meetings. Lab report Lab reports must be written in such a manner that every person with background in chemistry will be able to reproduce the experiment without any uncertainty or difficulty. Lab reports must be typewritten with double space format. No handwritten comments, charts, equations, diagrams, etc. allowed (‐10 points). A template format of the formal report is attached with this note. The lab reports are due the week after the experiment is done and to be submitted at the beginning of the next lab experiment. Late lab report will merit a deduction of 10 points/day including holiday and weekend.
A lab report must include: Title: Must be descriptive. Abstract: A brief explanation, its importance, main achievement. Introduction: Includes background, basic concept, motivation or main reason why worth doing. Experimental section: Must use precise scientific language, not to be too extensive, include all of the important detail, must not be a transcription as describe in textbook. Results and Discussion: The most important part of your report. Present the finding or data of the experiment, tables or figures must have a title/caption and a number, use scientific argument, observations of events, timing, and target compound characterization (attached spectra and their interpretation). Show calculations in this part. Conclusions: Closing statements, explain any general or new affirmation. References: Include the textbook and any source consulted while preparing your report. Quiz is given after a short lecture before starting the experiment without notifying and you are usually given 15‐20 minutes. Quizzed comprise of safety issues, pre‐lab information that you should aware of for the current experiment and everything about the previous two experiments conducted. All prepared compounds should be appropriately packed either in vials or in sealed ampoules and labeled. Labels should clearly indicate: chemical formula of a compound, date of preparation, amount of substance in grams and the author(s). The label should be attached to the above container. Academic dishonesty: All members of the University community share the responsibility and authority to challenge and make known acts of apparent academic dishonesty. Any student detected participating in any form of academic dishonesty in this course will be subject to sanctions as described in The UH Academic Honesty Policy. It is your responsibility to read and fully understand The UH Academic Honesty Policy. Cheating (pre‐lab/quiz/report) always merit an automatic ZERO for the activity at which it was committed. Plagiarism also merits an automatic ZERO.
Make‐ups lab will be allowed due to one of the following four reasons. If any student misses a class with any other reason, a grade of zero will be given for that experiment. Acceptable reasons for a missing experiment are: i) ii) iii) iv)
Illness (with physician's note); Death of a close family member or friend; Religious holiday (you MUST inform the TA of this IN WRITING by September 9th); An official university activity.
All experiments will be performed in groups of three. However, lab reports will be graded on an individual basis. The UH Academic Honesty Policy is in effect. Any students who need special accommodations are responsible for communicating these to the TA and/or the lab coordinator. Students are responsible for all broken/missing equipment and for checking out. In other words, you will be assigned for a drawer full of equipment at the start of the semester. At the end, you must give us back the same amount and type of equipment in the same or better condition. If you do not, you WILL BE CHARGED MONEY!!!! Dropping a class: Students who miss check‐in may be dropped. All other drops are under students’ responsibility. It is your responsibility to understand the University’s procedure for dropping a class. If you stop attending this class but do not follow proper procedure for dropping, you will receive a failing grade and will be financially obligated to pay for the class. Students must check the UH Academic Calendar for drop dates. PROVISIONAL SYLLABUS Week Date
