Appointments can be made if you want to be certain. Class Room: J-212 Class time: Monday and Tuesday, 1:30 pm – 5:30 pm. Textbook: CHL 191 laboratory manual. Evaluation policy: Report cards 45% Information project 5% Individual detailed lab report 15% Lab cleanliness 5% Final exam 30% There will be no supplemental examination for students who fail this course. Attendance: Attendance to labs is mandatory. See your instructor BEFORE or AS SOON AS POSSIBLE AFTER any missed laboratory session. Students must complete all labs or a grade of 0% will be given. Laboratory Safety: Safety equipment (safety glasses and lab coat) are mandatory at all times. Long pants give the best protection for your legs, and shoes with socks provide good protection for your feet (open toed shoes such as sandals are not permitted).

Laboratory Manual: This can be purchased at the bookstore. The cost covers the manual and the report cards. DO NOT FORGET YOUR MANUAL when you come to the laboratory session. Pieces of paper other than the lab manual and report cards will not be allowed in the laboratory. Report Cards: Will be provided to you during the laboratory session. Results, observations, and answers to questions must be submitted on the proper report card. One report card per experiment per student must be submitted. Report cards are due before 4:30 pm on the day following the laboratory session. Marks on late report cards will be reduced by 20% per day late. Course description: The CHL 191 course is an experimental course in which the students will learn various techniques used in chemistry, applying their knowledge of chemical concepts and phenomena as described in the CHM 191 course. General Objective: The general objective of the laboratory course is to initiate students in basic laboratory techniques and to inform them of the safe manipulation of chemical equipment and reagents and the correct disposal of chemical reagents and wastes. Students will be able to improve their observation, measurement and correlation skills. Specific Objectives: At the end of this laboratory course, the student should have: - - Developed sound safety habits in the laboratory. Managed first-level chemical wastes in a laboratory. Applied the common laboratory techniques used in general chemistry. These involved accurate measurements of masses, temperatures, and liquid volumes, the dilution of solutions, titration, filtration techniques, and gas volume measurement. Carried out simple analysis and inorganic synthesis. Written a formal laboratory report in accordance with standard format. Properly presented the experimental results in the laboratory report. Clearly described and discussed the observations and measurements. Carried out the typical calculations related to an experiment. Applied and understood the rules that determine the number of significant figures in experimental readings and results. Studied simple chemical phenomena in relationship with the theory of the CHM 191 course. The precision and accuracy of the results of each experiment reported on the cards will be evaluated. It is an objective of this course to learn how to present a laboratory report. Therefore, ONE formal laboratory report, based on an experiment of the student’s choice and in a suitable format, must be submitted by the end of the semester (no later than 4:00 pm on November 26, 2014. This report must be done individually and include the sections outlined in the laboratory manual. Success in the laboratory depends on preparation and understanding of the experiment before the laboratory period. At the beginning of each lab session, there will be a short quiz to assess the level of student preparation. Laboratory Final Examination (November 17 and 18, 2014): - 2 hour written examination. Topics described or discussed in the experiments (safety, procedures, techniques, and calculations) will be tested in the final examination. Neither the lab manual nor the report cards will be allowed during the exam. There will be no supplemental final examination. Missing Laboratory Sessions: If you miss any laboratory session, during which a new technique has been introduced, it will be your responsibility to learn it. Plagiarism: Any offence will be reported to the dean and an automatic grade of 0 on the assignment will be given. Further offences will be dealt with appropriately according to university policy.
