CHEM / CHEM CHEM CHEM A Good Lab Report. At every stage of an experiment, the accurate and unbiased recording of results is essential. Your lab report should be neat and legible and only written in pen or ink (blue or black ONLY). Wan, H., Organic.

Professor K - sample organic chemistry lab report


WHAT did you determine about it? Product identity was confirmed by melting point o C and infrared spectroscopy lack of aromatic hydroxide signal, presence of ester carbonylas well as a successful FeCl 3 test, indicating a high level of purity of the product.

Scheme I. Aspirin synthesis from salicylic acid. Note that a percent error for a melting point has abolutely no significance and should never be reported Both are low by 1 degree, and given similar melting point depression constants, would have similar levels of impurities. Don't perform calculations without thinking about their significance! Introduction Willow bark has been known to alleviate headaches and other pain for centuries. Hippocrates wrote of its organic chem lab report powers as early as BCE.

The acetyl derivative, acetylsalicylic acid ASAwas synthesized in by Felix Hoffman, which began being sold under the trade name "aspirin" by the Bayer Company several years later. This reaction is reversible, which is why aspirin commonly smells of vinegar, as the ASA hydrolyzes in air back to SA and acetic acid.

ASA does not react because the phenol group is acetylated. So, this lab report should include: theory of standard solution preparation including the reasons for the standardization of NaOH and amphoteric nature of KHP; reason for over-titration and back-titration; questions from manual. If this were a synthetic organic chemistry paper, the reaction mechanism would go here. DO NOT thank your professor or the stockroom for doing their jobs, your lab partner for being your partner, or your roommate for putting up organic chem lab report you and letting you use their computer.

While your gratitude is appreciated, it is unnecessary and unprofessional, organic chem lab report. This, and much of the information presented here, may differ from what is stated in your lab manual or class. You should consider who is grading your report in deciding how to write it. If someone was particularly instrumental in helping you with equations, etc, they should be mentioned here. If your professor stimulates you into pursuing a graduate career in chemistry or discourages it, for that matter!

The "references" section is for items which you "footnote" in the text. Online research can be useful in locating reference data, but caveat emptor- the base source should organic chem lab report cited and you should verify that the material you are citing is actually in the base source.

An "articles consulted" or bibliography section may be included for reference materials you used but which you do organic chem lab report directly reference in the text of your report, though this is nonstandard. Please note that different journals have different standards- there is no universal agreement on reference format, but you should use ACS format. Wang, S. Brown, organic chem lab report, H. Academic: NY,Chapter Kevin Organic chem lab report, Ph.

FAIL the browser should render some flash content, not this. FAIL there is a non-flash navigation bar at the bottom of the page. It makes your paper appear unprofessional. Samples are "prepared" and graphs are "generated" or "produced" in the lab- nothing is ever "created, organic chem lab report. Masses may be "taken" or "found" or "discovered", but chemicals should not be "massed" used incorrectly more and more frequently and absolutely never "weighted. No contractions.

Again, this is formal writing. Do not attempt to B. The confusing misuse of big words is NOT eloquent. You just sound like a dumb politician trying to sound intelligent. Expressing yourself so that the reader "kinda gets what you mean" is not sufficient. All data must be expressed with the correct number of significant figures.

Spelling and grammar errors are not acceptable. 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. You cannot possibly be too lazy to use it. You can simply tell the computer to ignore those. But it will also find your legitimate errors. Whether or not English is your native language, it IS the internationally accepted language of science. USE your school's writing center!

Verbs should not be used as adjectives in an effort organic chem lab report economize your writing. It just makes for awkward writing. Chances are they are unnecessary. Remove them. Many of the things you use in the lab are precision measuring devices.

Thus they are "instruments" not "machines. That being said, YOU are operating the instrument, thus "an IR spectrum was acquired using a SmithsIR" is correct, while "the graph was measured by a SmithsIR organic chem lab report is incorrect for no less than 3 reasons.

You can quantify something "via" a technique, but using "by" the technique makes it sound like the technique did it all by itself. Sample calculations must include 1 complete set of calculations using real data organic chem lab report the lab.

The set of calculations must also include the propagation of error, if required. Include all units. Express numbers in correct scientific notation with superscripts 3. These computers are amazingly adept at superscripts whereas old typewriters were not. Justify everything. If you say one method is better than another due to cost, the dollars involved had better be cited. All error must be explained. Be specific.

Redundancy is not good, organic chem lab report. This includes repetition both within and between sections of your report. Precise and accurate scientific writing is required. The states of matter saqg are NOT subscripted. You may italicize the letter if you are so inclined. The numbers in formulas denoting multiple atoms or functional groups ARE subscripted. Ex: AgNO 3 aq. Chemical techniques, e. The only exception to this rule is in the report title. Table captions are not an exception this is the one and only difference between these instructions and The ACS Style Guide- I choose to make this rule because inexperienced writers have proven incapable of deciding what words are important, and unacceptable inconsistencies generally result.

Be sure abbreviations are correct, too: mL, mol, organic chem lab report, etc. They are all critical to your development of superior scientific writing skills. Follow them or suffer the consequences. Acknowledgments note the correct spelling of the word DO NOT thank your professor or the stockroom for doing their jobs, your lab partner for being your partner, or your roommate for putting up with you and letting you use their computer.

Preparation of standardized NaOH solution mL of 0. Appendix II- IR data note that "spectra" is the plural of "spectrum" and that spectra not "graphs" are acquired using a "spectrometer" or "spectrophotometer" the model number of which should be noted in your experimental sectionwhich is an "instrument" not a "machine".
