The previous studies have shown Attention Deficit Hyperactive Disorder occurs with greater frequency in children exposed to pesticides. This study, using mice and post-mortem brain analysis, attempted to provide a biological explanation as to why ADHD would result from pesticide exposure. After exposing pregnant mice to pyrethroid pesticides, the offspring were observed and brain structures analyzed. According to the researchers, mice exposed to pyrethroid pesticides during development exhibit hyperactivity, impusive-like behavior, deficits in working memory and deficits in attention.
Product identity was confirmed by melting point oC and infrared spectroscopy lack of aromatic hydroxide signal, presence of ester carbonylas well as a successful FeCl3 test, indicating a high level of purity of the product. Aspirin synthesis from Organic chem lab report 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. Hippocrates wrote of its curative 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: If this were a synthetic organic chemistry paper, the reaction mechanism would go here.
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.
While your gratitude is appreciated, it is unnecessary and unprofessional. 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 be 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 not 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.

At every stage of an experiment, the accurate and unbiased recording of results is essential.
Your lab report should be neat . Basic Format of a Chemistry Lab Report (printable version here)Abstract - The abstract is a brief summation of the experiement.
It should not exceed two hundred words and should explain, in a concise manner, the purpose of the experiment, how the experiment was conducted, and the results gained.
