CHM151L-General Chemistry I Syllabus
General Information: Offered Fall, Spring, and Summer
1-hour of Laboratory Science credit
Instructors: All faculty with appointments in the chemistry department are eligible to supervise CHM151L sections. All sections will utilize graduate, and/or undergraduate teaching assistants.
Course Prerequisites/Co-requisite: CHM130 or CHM151
Distribution Block: If taken with CHM130 or CHM151, student can receive 5 hours of lab science credit.
Course Description: CHM151L is the first semester of a 1-year sequence appropriate for pre-professional, science, and engineering majors. Principles, practices, and applications of contemporary laboratory chemistry will be addressed. As a liberal studies course, CHM151L addresses the essential skills of scientific inquiry and quantitative reasoning, and the theme of environmental consciousness. Students will have hands-on experience using the scientific method to describe, quantify, and solve problems of a chemical nature including several chemical processes that have direct impact on the environment (such as chemical reactivity and acid/base reactions).
Course Objectives: Students will be able to:
1. Demonstrate basic laboratory skills. (Scientific Inquiry)
2. Describe and demonstrate safe laboratory practice. (Scientific Inquiry)
3. Utilize scientific notation and dimensional analysis in solving problems of chemical interest. (Quantitative Reasoning)
4. Predict, analyze and test experimentally the chemical and physical properties of matter. (Environmental Consciousness, Quantitative Reasoning, Scientific Inquiry)
5. Determine the numerical value of chemical concentrations and physical states. (Environmental Consciousness, Quantitative Reasoning)
6. Predict, analyze, and experimentally confirm the products of a chemical reaction. (Environmental Consciousness, Quantitative Reasoning, Scientific Inquiry)
Specific Skills: By the end of this lab you will be expected to be able to accurately use a volumetric pipet, pipettor, buret, volumetric flask, mohr pipet, balance, thermometer, and graduated cylinder in safely conducting titrations, dilutions, weighings, and other lab procedures. You should be able to calculate and/or use molecular mass, moles, molarity, percent-by-mass, density, m1v1=m2v2, PV=nRT, plot and use graphs.
Course Structure and Approach: CHM151L will address chemistry -- the science of change, through hands-on laboratory exercises. Using standard laboratory practice and equipment, students will measure, quantify and describe chemical properties, and identify chemical unknowns based on the results of their measurements.
Course Outline:
I. Measurement of mass, volume, density, and fermentation (2 periods)
II. Identification and Quantification of a metal chloride solution concentration (1-2 periods)
III. The study of chemical reactivity (1-2 periods)
IV. Quantification of the waters of hydration of ionic compounds (1 period)
V. Identification of ions in salts (1 period)
VI. Acid-Base Titration (2-3 periods)
VII. Determination of molar mass (1-2 periods)
VIII. Thermal properties of matter (1-2 periods) - Optional
Instruction and Evaluation Methods: The primary instructional methods utilized in CHM151L are hands-on laboratory exercises. Demonstrations of laboratory methods and techniques will prepare the student to make independent observations of chemical phenomenon, and measurements of chemical properties.
Assessment of Outcomes: A report of experimental observations and results will be completed for each of the seven laboratory exercises. Each lab is designed to address the content areas listed in the course outline. Assessment of student learning outcomes is based on the correct identification of the composition or concentration of unknown materials through application of the scientific method (scientific inquiry, quantitative reasoning), and on the results of a hands-on practical laboratory examination (quantitative reasoning). Both of these assessment tools test the student's competence with basic laboratory methods and techniques.
Textbook and Required/Optional Materials: Required: General Chemistry I Laboratory Manual, CHM151L, for 2008-2009 by Hayden McNeil and indirectly vented goggles. Both items are available in the NAU bookstore or University Text and Tool and must be purchased before the second lab period. If there are no manuals in the textbook area ask for help at the textbook desk. Optional: lab coat or apron. More information on this course can be obtained at the Chemistry Instructional Laboratories Homepage at: http://jan.ucc.nau.edu/~jkn/Labs.html
Course Grade: The course grade is based on a total of 1000 points. 610 possible points are earned by the proper identification of unknowns and completion of experiments. 200 points are based on the results of a hands-on practical examination. The Loncapa Pre-labs and Post-lab questions are worth 120 points. Points and grades will be assigned as follows:

Experiment unknown report sheets will be graded pass (full credit), partial credit (about half credit), or repeat (about 20-30%). Points will be assigned as noted above. A pass indicates that the experiment was done correctly and the techniques were mastered. Partial credit indicates that there were small technique or calculation errors but no gross errors. If you have time, it would be a good idea to do experiments with partial credit over with a new unknown. A repeat indicates that major technique or calculation errors were made and the experiment should be repeated. Any experiment can be repeated with a new unknown from the lab prep stockroom (216) but late points will be deducted from the score. To repeat an experiment, analyze a new unknown checked out from the Lab Prep Stockroom (216). Use a new report sheet from rm 221 (chemistry computer lab) and be sure to staple any new calculation checks and the original unknown report sheet to it! Report sheets turned in after deadline dates listed later in the syllabus will face a penalty as noted above for late work. Grades will be posted on the web and updated at least twice a week. To view your current grades on the web go to: http://jan.ucc.nau.edu/~jkn/Labs.html
Extra Credit: When you have passed all of the unknowns, you may try to earn up to 60 extra credit points by doing for doing one or more of the following experiments worth up to 20 points each: Bonus Titration, Thermochemistry, and Fermentation experiments found on the web at the CHM151L homepage. Be sure to read the requirements carefully. You must do all the experimental work, calculations, and writing yourself – do not use another student’s work. The TA must sign and date the piece of paper used to collect the data during the period(s) it is collected. Attach this data sheet to mini report.
Pre and Post Lab Questions, Outlines of Experimental Procedures, and Other Requirements: In order to safely complete an experiment with understanding, students must prepare in advance. Students must therefore read experiments, outline the experimental procedures (on the report sheet at the end of the experiment or on notebook paper if you need more room), and do a web-based pre-lab on Loncapa before they come to lab to start that experiment. When an experiment is completed many of the calculations can be checked using calculation checks. Do any graphs where required. Copies of graphs and the calculation checks along with the experimental procedure outline must be stapled to the report sheet. All experimental data and questions must be completed for the experiment report sheet to be graded, otherwise it will be returned un-graded (Five points may be taken off for minor issues of missing or incorrect answers). Finally complete the Loncapa post-lab questions for the experiment. Loncapa and the calculation checks are online resources that will be introduced by your TA. Exact due dates are listed later in the syllabus (No exceptions to these deadlines).
Lab Performance: Proper lab technique, safety, and cleanup procedures are required in this lab. Poor technique such as using the balance or pipettors incorrectly, unsafe behavior such as not wearing goggles can result in the loss of 5-25 points per incident. You are required to clean any used glassware and your work station at the end of every lab period. To clean glassware rinse with hot tap water after use and once with RO water in RO tub or from your wash bottle. Fill your wash bottle with RO water for this purpose and other uses. Don't use the RO water tap for rinsing glassware. This valve is not designed for this level of use. Use soap if needed. Always wash glassware before you put it away. If you break or lose any glassware or equipment you must replace it at the chemistry stockroom and be billed. Your workstation must be complete at the end of each lab period for the next student. There will be 5-25 point deductions for each problem depending on the magnitude of the infraction. Extra credit points may also be given for excellent lab performance above and beyond. If you remove glassware from another student's bin or workstation you will be asked drop the lab. You will be completing a contract on issues regarding lab performance.
Safety: Safety in the laboratory is of great concern to the chemistry department. You are expected to be familiar with and adhere to the chemistry department safety policy noted in the lab manual at all times while in the laboratory. Be informed about the hazards of chemicals before you use them by doing a risk assessment for each experiment. Every chemical in the laboratory is labeled with a hazard code to assist in this process. If you would like additional information, material safety data sheets (MSDS) for every chemical used in this lab are available for your reading in room 212. You will do a web based MSDS tutorial-quiz to become more familiar with using them. You must print the certificate indicating you have completed the tutorial and turn it in to your TA before you are allowed to do any labwork beyond experiment 1 and checkout an unknown packet. The tutorial can be accessed on Instructional Labs Homepage by clicking on the “Safety Information” link and then on the “Quiz” link. There is much useful information on this site such as MSDS information.
There is a remote possibility that medical issues such as respiratory conditions, allergies, pregnancy, etc. may be aggravated by chemicals used in this lab. Please talk to your instructor and TA if you have any questions about taking this class with special medical conditions. Phones are located in the hallways for contacting campus security at 3-3000 in the event of an emergency. You will also be expected to clean up any small spills you make and your work area with a damp sponge (rinse out sponge after use) every lab period or face a 5 point penalty. Always wear goggles in lab and wash hands at lab’s end.
Lab Practical: The laboratory practical will be given the first 90 minutes of the last lab period. The practical must be taken in your regular lab section. The practical is an experiment using many of the techniques covered in this course. The lab practical instructions and practice problems found on page 79 and 80 of your lab manual will explain more about the lab practical (Answer to practice problem is posted on CHM151L web page). A help session will be given before starting the lab practical.
Academic Dishonesty: The Department of Chemistry strictly enforces the University’s policy on academic dishonesty. Sanctions imposed for academic dishonesty include receiving an F for the course or expulsion from the University. Each student must do the pre-lab work, lab work and calculations individually. Using another student’s unknown, unknown #, data, or results will be treated as academic dishonesty. In addition, if you repeat an experiment you must check out a new unknown from the prep stockroom (216). Using the same unknown number twice will be considered academic dishonesty.

*All offices are by building number first and then room number (building 20 (chemistry), 88 (Wettaw) and 17 (New Lab Facility).
The instructor will be available during normal lab times either in the lab room or in their office. They can also provide help during their office hours. Instructor office hours will be announced the first day of lab and will be posted. The TAs will be available to help before, during, and sometimes after the laboratory. Due to the large demand for CHM 151L, students may lose their spot in lab if either of the first two lab meetings is missed. These students will then be required to drop the lab course.
Schedule:
First week activities include: Meet in your lab room and read the syllabus. Next go to 221 for a lecture on the course, the syllabus, safety, etc. Videos on lab safety, MSDS, the balance, and pipettor will be shown. The TA will demonstrate the use of the MSDS Tutorial, videos, grade check, and other resources as accessed through the labs web site. Each section will then go to their lab room and safety features will be reviewed and assignment one completed and turned in to the TA.
Homework Due Before 2nd Lab Period: Read introduction and experiment one, outline exp.1 experimental procedures, complete lab performance contract, calculator check, and do web based MSDS tutorial/quiz and print certificate for second week. Please note that the Loncapa Pre and Post Lab System will not be available for use until Monday, 9/8.
Before every lab:
1. Read the experiment, briefly outline the experimental procedures on the report sheet or sheet of paper, and watch videos suggested in the lab schedule.
2. Complete the loncapa pre-lab before the experiment is started before the deadline noted later in this syllabus.
3. Complete any special work due as noted in the schedule later in the syllabus or in the lab manual.
Every lab period will have a similar format:
4. Come to lab on time or early if possible and sign in and get out glassware and equipment needed but do not work with solutions or chemicals yet! (3 points for signing in within the first 5 minutes of lab!). If you come every week on time until you pass all the experiments you will get an extra 6 points for 45 points total.
5. Five minutes into the lab the TA will provide information on the experiment and do demonstrations.
6. Put on goggles and other safety gear as needed and conduct the experiment.
7. Cleanup by washing glassware, putting stuff away correctly, and wiping down your work areas with a damp sponge. Points may be deducted for not cleaning up on time and working safely.
8. When done put away your goggles, exit the lab and wash your hands at the sinks in exit area.
After the experiment is completed:
9. Do any calculations when the experimental work is completed and printout any graphs or spreadsheets.
10. Complete any web based calculation checks to insure your calculations are correct and print copies.
11. Answer any post-lab questions on the report sheet and staple any experimental procedure outlines, graphs, spreadsheets, calculation checks, or post-lab questions to the report sheet. (for repeats of unknowns staple this old work on back of the new report sheet).
12. Copy the key information from your report sheet into the blanks at the end of the experiment in the lab manual.
13. Turn in the report sheet at the Lab Prep Stockroom (216) window and complete the loncapa post-lab questions before the deadlines noted in the syllabus.
