; Hendrickson, D.N. Note that a percent error for a melting point has abolutely no significance and should never be reported... For example, an experimental melting point of 1 degree for a compound with a melting point of 2 degrees would have a 50% error, while an experimental melting point of 99 for a compound with a melting point of 100 would only have a 1% error. Whether or not English is your native language, it IS the internationally accepted language of science. The only exception to this rule is in the report title. Redundancy is not good. Components of a Laboratory Notebook. ", Although it IS permissible to use the word "weight" instead of "mass," NEITHER should be used as a verb. You just sound like a dumb politician trying to sound intelligent. Don't perform calculations without thinking about their significance! TitleOfBook, 1-WordPublisher: CityofPublication, YearOfPublication, PageReferenced. endobj Introduction Instead of writing “I added 5.0g NaCl to 50mL water” just write “5.0g NaCl was added to 50mL water.” Whoever is reading your lab KNOWS you and/or your partner did it… your name is on the cover page! If your professor stimulates you into pursuing a graduate career in chemistry (or discourages it, for that matter!) Avoid the use of the word “it”- your goal is to be CLEAR and CONCISE. Hippocrates wrote of its curative powers as early as 400 BCE.1 Studies on willow bark led to the dicovery that the active ingredient is salicylic acid (SA), which was first synthesized in 1853 by Charles Gerhardt.2 Since SA causes upset stomachs for many people, a method of obtaining a milder product with similar curative powers was an area of intense research. No contractions. USE your school's writing center! Academic: NY, 1955, Chapter 14. All error must be explained. Chemical techniques, e.g.- mass spectroscopy, may use capital letters for their abbreviations (e.g.- MS), but are not capitalized when written out. There are these really cool things called computers now where all you have to do is press one button and the spelling and grammar of your document are checked. An "articles consulted" or bibliography section may be included for reference materials you used but which you do not directly reference in the text of your report, though this is nonstandard. since KHP is a monoprotic acid, assume 25mL of 0.1M KHP (1 mol acid neutralizes 1 mol base) Writing an Organic Synthesis Lab Report . You won’t turn it in yet, but your TA will initial it during the lab. Do not attempt to B.S. Watch Out For Unnecessary Capitalization… This Is Really Not A Good Idea When Writing A Report Filled With Chemical Symbols. Thus, “the number of moles of chloride” or “the amount of chloride” can be determined, but statements such as “the moles of chloride” make no sense grammatically or chemically. This includes repetition both within and between sections of your report. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Chem. This is not the third grade, when you (hopefully) stopped writing “the subject of my book report is…” so NEVER use the phrase "in this experiment" or any equivalent thereof ANYWHERE in your report. Yes, the computer will find words and phrases that it doesn’t understand which you wrote correctly. The report conveys what you have done in a concise, organized and easy to read fashion. See your lab manual and/or a statistics book for a discussion of significant figures, especially with regard to standard deviation. journal accessed online Masses may be "taken" or "found" or "discovered", but chemicals should not be "massed" (used incorrectly more and more frequently) and absolutely never "weighted.". If someone was particularly instrumental in helping you with equations, etc, they should be mentioned here. ?�ry���Ʉ]|�dg?�86ߞ����$p�;ü Willow bark has been known to alleviate headaches and other pain for centuries. All data must be expressed with the correct number of significant figures. The laboratory report is a formal report of the experiment performed. SOMEONE OF SIMILAR TRAINING SHOULD BE ABLE TO REPEAT THE EXPERIMENT USING THESE INSTRUCTIONS AND OBTAIN YOUR RESULTS. We hope that this collection will enable organic chemistry educators to share with other universities valuable experiments performed in the undergraduate teaching laboratory. Example Lab Report for Organic Labs Actual lab report is in black; notes about how to write reports are in red . You can simply tell the computer to ignore those. PROOF READ!!! Redundancy is not good. Iron(III) chloride (FeCl3) reacts with phenols to form brightly colored complexes, thus providing an excellent means for testing the effectiveness of the ASA to SA conversion. Online research can be useful in locating reference data, but caveat emptor- the base source should be cited and you should verify that the material you are citing is actually in the base source. Express numbers in correct scientific notation with superscripts (3.0x10. If the units of the answer don’t match the calculation, the math can not possibly be correct. ***** BEGIN SAMPLE ORGANIC CHEMISTRY LAB ***** The confusing misuse of big words is NOT eloquent. This resource will allow the task to come as a second nature! AuthorLastName, AuthorFirstInitial; OtherAuthorLast, OtherAuthorFirst. Experimental 1994, 116, 8376. If you don't want to buy the book, the references section is available online for free (as of 9/2011). Soc. 4 0 obj Product identity was confirmed by melting point (133-134oC) and infrared spectroscopy (lack of aromatic hydroxide signal, presence of ester carbonyl), as well as a successful FeCl3 test, indicating a high level of purity of the product. ), Preparation of standardized NaOH solution, 500mL of 0.1M solution desired ; Nachod, F.C., Eds. No colloquialisms. Follow them or suffer the consequences. Verbs should not be used as adjectives in an effort to economize your writing. TitleOfJournalAbbreviated, YearOfPublication, Volume:IssueNumber, PageReferenced. (ASA does not react because the phenol group is acetylated. Read your lab OUT LOUD...if it makes no sense, re-write it! Reports should be typed. (0.1mol NaOH/L solution)*(0.5L solution)*(40.01g NaOH/mol NaOH)*(1 pellet NaOH/0.1g NaOH) = 20 pellets NaOH needed, assume titration with approximately 25mL KHP solution ; Hendrickson, D.N. assume each NaOH pellet weighs 0.1g %���� Do not use the latter word. ETC ETC ETC. Again, this is formal writing. Never fear, though! your way through a lab report...if you don’t understand the material, seek help! Results and Discussion journal It’s necessary to add brief comments concerning each of them. Sample calculations must include 1 complete set of calculations using real data from the lab. MANY OF YOU HAVE NEVER USED ANYTHING OTHER THAN GOOGLE FOR RESEARCH UP TO THIS POINT IN YOUR EDUCATION... THAT IS VERY SAD. Am. You should consider who is grading your report in deciding how to write it.) The references should be in the following format, per The ACS Style Guide For example, “Ten grams of NaOH was weighed”, not“I weighed 10 g of NaOH.” Using “we” or “I” in a lab report is very rare, it only pertains to comparison with others’ results. While your gratitude is appreciated, it is unnecessary and unprofessional. ************ BEGIN SAMPLE ORGANIC CHEMISTRY LAB ************, Acetylation of Salicylic Acid Welcome to the Organic Chemistry Laboratory Experiments repository at OpenBU. All lab procedures are available to download and modify, and we encourage the submission of new experiments to the database. Reviewing Every Step. Be sure abbreviations are correct, too: mL, mol, etc. Watch especially the use of “affect/effect,” “it's/its,” “their/there,” “passed/past,” etc. (ie- How you found the source is irrelevant, but claiming that "the internet said the info was in that source" when the information is not, or the source doesn't exist or is incorrect, is a great way to get your paper rejected.) Scheme I. Aspirin synthesis from salicylic acid. PRESENT TENSE. Both are low by 1 degree, and given similar melting point depression constants, would have similar levels of impurities.
