CHEMISTRY 130LL LAB SCHEDULE Spring 2014 You must download and print the CHM 130LL laboratory experiments from the CHM130LL Website (http://web.gccaz.edu/~kimld88531/chm130Lab.htm). If you are using an off-campus computer, you need to install a copy of Adobe Acrobat Reader (http://www.adobe.com/products/acrobat/readstep2.html) on your computer to view and print these documents. You must print and read the lab experiment BEFORE coming to lab. The references in ( ) are sections in the 7th edition textbook that you should review before coming to lab. You must arrive for lab on time. Your instructor will introduce new techniques, procedures, and safety as well as briefly review the theory and calculations at the beginning of each lab. Students who arrive too late to receive critical lab and safety information will not be allowed to complete the lab. The following is a tentative schedule: Week Dates Experiment and/or Activity Welcome!

Some experiments require specialized equipment, which will be dispensed at the instructor's station. When you check out unknowns for the experiment, print your name and unknown number, and record the unknown number on your Lab Report. Before leaving lab, properly dispose of waste (see experiment for details), and clean and return all equipment to the appropriate place. Wash your hands and bench before you leave every lab. STUDENTS ARE REQUIRED TO WEAR GOGGLES IN THE LAB AT ALL TIMES, EXCEPT AS SPECIFIED BY THE INSTRUCTOR. Students must wear closed toe and heel shoes, pants/skirt below the knee, and shirts with sleeves in lab. Jeans/pants with holes from the knee up are not allowed. Chemistry Department Safety Rules 1) 2) 3) 4) 5) 6) 7) 8) 9) 10) 11) 12) 13) 14) 15) 16) 17) 18) Wear approved goggles at ALL TIMES in the laboratory. Do not open the goggle vents. Do not perform unauthorized experiments. Only your laboratory instructor may authorize special experiments. Wash any spilled chemicals off your person with water as quickly as possible. Do not touch any chemicals without receiving specific instructions to do so from your instructor. Do not taste any chemicals. Smell chemicals only when directed and then with caution. Insure that any heated glass or metal equipment has cooled adequately before handling. Use caution in handling all glassware. If a cut occurs, rinse the wound with cold running water until you are sure there are no small pieces of glass in the cut. Before you plug in electrical equipment, make sure that the cords are not damaged. Keep cords away from all hot surfaces. Know your laboratory’s location for the fire extinguisher, eye bath, and shower. Wear closed-toe shoes that cover the top of the feet, and appropriate clothing that covers the student from neck (including shoulders) to below the knees. Jeans with any holes from the knee up are not allowed. Keep long hair tied back at all times. Consult the lab procedure for handling waste chemicals. You are responsible for cleaning the equipment you use as well as your lab workstation. You must wash your hands with soap and water and wipe your lab bench down with a damp paper towel after every lab. Report any personal injury, no matter how slight, to your laboratory instructor. Always read your laboratory exercise completely prior to actual lab time. Be aware that an unprepared worker is an unsafe worker. Upon request, we can provide a list of chemicals used for the semester, as well as the MSDS reports. CHM Department Policies 1) All students who miss the first lab meeting will be dropped from the roster. 2) All lab students must complete their safety training before performing any experiments. 3) You are expected to be on time for lab. You will not be allowed to work in lab if you miss any part of the vital safety information and/or demonstrations of techniques. 4) Student lab grades will be reduced by 10% for not having a copy of the lab procedure. 5) Students will not be allowed to perform the lab without approved goggles, closed-toe shoes that cover the top of the foot, and without clothing that covers the student from neck (including shoulders) to below the knees. These students must make-up the lab. It is the student’s responsibility to arrange a make-up lab at another time. A locked drawer will be provided for each lab session to store goggles for the semester. 6) Lab make-up is at the discretion of the instructor and depends on available space. Make-up is allowed during regularly scheduled lab sections and only during the days that it shows on your schedule. The lab schedule is posted on the chemistry web site. No more than two labs may be made up. A make-up form needs to be filled out and attached to the lab report. Note: If your lab has only one section or is at the end of the lab week, you may not be able to make up lab. 7) If you miss more than 2 labs, without making them up, you will receive a grade of W or Y. 8) Students who withdraw from the lecture within the first 10 weeks must also withdraw from the lab. 9) If you do not turn in the lab report before you leave, obtain the instructor’s initials on your data sheet before leaving the lab. 10) Students must always turn in individual lab reports even when working in pairs on a lab procedure, unless stated otherwise. Your report should be in your own words and not copied from your lab partner. 11) During the semester you will be charged if you break any of the special equipment. Your instructor will inform you of the replacement costs and the procedure to follow for payment. 12) Arizona Statute ARS15-151 specifies that every student, teacher, and visitor in public and private schools, community colleges, and universities shall wear appropriate eye protective wear while participating in or when observing vocation, technical, industrial arts, art or laboratory science activities involving exposure to: molten metals or other molten materials, cutting, shaping and grinding of materials, heat treatment, tempering or kiln firing of any metal or other materials, welding fabrication processes, explosive materials, caustic solutions, radioactive materials.
