Is it possible to use materials found in high school chemistry labs to extract and subsequently detect cocaine on dollar bills? Let me know what you think after reading this blog post!
In the June 6th, 2016 Chemical and Engineering News magazine put out by the American Chemical Society, C&EN talks with Deborah Blum, journalist and author: From the article’s description, ‘The Poisoner’s Handbook’ writer talks about the beauty of chemistry and why she wants people to know more about it.
In this Activity, students develop fingerprints using the cyanoacrylate fuming method on different types of surfaces. They investigate the technique’s effectiveness and test the effects of changing the temperature and humidity of the fuming chamber.
In this Activity, students collect fingerprints and use three different methods to develop them: fingerprint powder, ninhydrin solution, and silver nitrate solution. The Activity could be related to the solubility of polar and nonpolar molecules, precipitation reactions, and oxidation-reduction reactions.
