When data analysis involves quantitative processes, a sample calculation must be shown for each computation or each step in a series of computations. When data analysis involves reasoning with qualitative data, such as identifying the substance in an unknown, you must verbally describe the relationships between your observations andĬonclusions. You can lose credit forĭata analysis includes reasoning and formulating conclusions that are based on descriptive or qualitative data as well as numerical computations based on quantitative data. On a side note, notice that buretreadings DO NOT have to start at 0.00 as long as you know where you started, and buret readings always have 2 decimal places. Data tables areĪlways a good idea! Simple calculations (such as addition and subtraction) may be added to data tables, however, the calculation must still be shown in the Analysis section. The data section must be organized and consistent with any format suggested in the laboratory manual. The first titration was the lightest in color of the three titrations and the second titration was theĭata include observations in addition to numerical measurements. We took our final buret reading when the solution in the flask changed from colorless to pale pink. Indicator Used: Phenolphthalein, 2 drops for each titration You must rewrite all the data from your lab notebook, attaching lab notebook pages and referring to them is NOT adequate and will receive no credit for this section. IDENTITIES of all solutions, CONCENTRATIONS of known solutions, starting and ending VOLUMES in a titration, and UNKNOWN NUMBERS. Be careful to include all of the details! This would include UNITS (such as mL, g, atm, etc.), This is a section where it is easy to miss lots of points for simply leaving out information. Procedure written in the lab manual, this includes glassware and concentrations, as well as chemicals.

To the procedure, for example, if the lab manual calls for HCl and we used HBr instead, that change would need to be stated after the reference. The title of the experiment, the name of the lab manual, and the page numbers on which the lab (the whole lab, not just the procedure) can be found. However, you must give a complete reference to where the procedure can be found. You do not need to write out the procedure unless explicitly instructed to do so. Procedure: "Titration of an Acid and a Base", Chem 116 Laboratory Manual, PurdueUniversity, Fall 2003, pp. You should put the objective in your own words, not merely rearrange the words used in the lab manual. That is plagiarism and you will receive no credit for this part of the report. The objective cannot be a verbatim, unreferenced restatement of the objective or purpose Objective: The purpose of this lab is to titrate an acid, HCl, with a base, NaOH, in order to determine the concentration of the base. Teaching assistant that there was a problem with your group and that person may not receive credit for the experiment.

If a lab partner fails to help write the report, in spite of your best efforts to include that person, you may leave that person's name off the report. The report must always include the title of the experiment, your name along with your lab partners' names, your section number, the date the lab was completed and turned in. Project Summary Report for Titration of an Acid and a Base CHEM 115 If you have any questions about what appears in this example, talk with your teaching assistant or contact the course The BLACK text is what will appear in the report. We put this together so that you know what we will be looking for in your reports. However, you can use thisĪs a guide for organizing your CHM 115 reports.

This is an example lab report from the CHM 116 WebCT course that has been modified so the cover page is consistent with the Fall 2004 CHM 115 format described in your lab manual.
