ii iii iv Title of the experiment Reference i e complete reference of the experiment including title of the lab manual author edition and page number of the experiment in the manual etc Include any changes to the procedure that you know you will make Short introduction Summarize in a few sentences about the background and the goal of the experiment Outline the kinds of technique that you will use in the experiment Procedures flowchart format v Pre lab study questions MUST show ALL your work complete ONLY 1 2 4 5 6 on page 4 of the handouts Note For question 2 you may assume that for EACH dilution process each piece of equipment can ONLY be used once and you can also assume that no combinations are allowed for the same kind of equipment i e you don t need to worry about using the combination of a 10 mL and a 5 mL pipet in a single dilution process Note The on line resources listed above may be useful when working on the study questions CHEM 14BL Report Guideline for Experiment 2 Pre lab Report is due at the beginning of the lab section Refer to the laboratory syllabus for the due date for both the pre lab and post lab report Both pre lab and post lab reports MUST be written inside your LAB NOTEBOOK The procedure for this experiment is provided as a handout NOT THE ONE IN THE MANUAL II Pre lab Guideline Report Continued vi MSDS information refer to the MSDS handout on how to use this resource on line Look up the following properties for Brilliant Blue FCF Note for this compound use the CS ChemFinder Web site refer to the MSDS handout for the Web address You should record the following MSDS information in your notebook for the chemicals listed above Printouts directly from Web pages will NOT be accepted for grading Important Reference the site i e write down the URL address that you used for each of the chemical a b c d e f Product Name Chemical Formula Formula Weight Melting Point Boiling Point and Density Health Hazard Data summarize in your own words Spill and Disposal procedures summarize in your own words Note Not all information is available for this particular compound Make sure you check all the links in the CS Chemfinder Web site If a particular information could not be found cite the URL address of the link s that you used to search for that particular information vii Data observations start a NEW page in your notebook for this section Note Start a NEW page in your notebook for this section The previous material will be turned in at the beginning of the period this page will be turned in at the end of the lab period refer to item 10 on page 5 of the handout CHEM 14BL Report Guideline for Experiment 2 Refer to the laboratory syllabus for the due date of the post lab report Post lab report MUST be written inside your LAB NOTEBOOK The procedure for this experiment is provided as a handout Post lab Report Guideline This is a GROUP Report i e TURN IN ONLY ONE POST LAB REPORT PER GROUP Before attempting to work on the group post lab report please take a moment and read the following items carefully Definitions of Group Report and or Group Experiment 1 All members in the group MUST contribute equally when working on the experiment as well as writing the post lab report 2 Each group member must prepare ahead of time when writing the reports This means review materials from lectures or from your Chemistry textbook or from on line resources on certain topics that are relevant to the concepts when writing the reports Contribution to the group work is meaningless if a group member does not understand the concepts behind the experiment 3 It is the responsibility of the group members to plan ahead on when they should get together to work on the report In other words maintain good communication between group members 4 It is the responsibility of each group member to honestly describe the work that they did during the experiment and in writing the report No one should take advantage of the other group member Report to the course instructor or your TA if you feel that other group members are taking advantage of your work 5 Each member in the group MUST understand the concepts behind the ENTIRE experiment regardless of which portions of the report or experiment a person is responsible for This is especially important for the exams CHEM 14BL Report Guideline for Experiment 2 Refer to the laboratory syllabus for the due date of the post lab report Post lab report MUST be written inside your LAB NOTEBOOK The procedure for this experiment is provided as a handout Post lab Report Guideline This is a GROUP Report i e TURN IN ONLY ONE POST LAB REPORT PER GROUP Useful definitions for the report w v is defined as weight in grams of solute 100 mL of solution ppm is defined as mg of solute L of solution ppb is defined as g of solute L of solution Note The Beer s law tutorial on line resource listed on the first page of this report guideline may be useful to you when writing the post lab report A Data Data Analysis Write out the name of each group member on your report as well as the individual responsibility when performing the experiment and writing the report i Set up a data table with columns for wavelengths you collected for your spectrum and the absorbances for the solutions you collected Fill in the experimental data on the data table At this point you will only have data entries for one row and one column of the data table You will fill in the rest of the data table later on in the report ii Description of the serial
