This experiment in chemical kinetics can be conducted using materials as simple as a smartphone, hydrogen peroxide, sodium carbonate solution, and blue food dye! The experiment is useful when discussing the order of rate laws with respect to reactants.
This post describes some simple experiments using various coins and neodymium magnets that connect to the 2019 National Chemistry Week theme of Marvelous Metals!
The June, 2018 issue of the Journal of Chemical Education contains an article that describes a simple, yet fascinating experiment that you and your students are going to love! It involves the use of butterfly wings from the genus Morpho. I obtained some of these wings and enjoyed experimenting with them. You will too!
You are likely aware that diamonds are converted - albeit slowly - to graphite under normal conditions. Thus, diamonds don't last forever, in contrast to the popular advertising slogan. However, did you know that you can use chemistry to prove that diamonds are not forever? It's simpler than you think...
The September 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: reticular chemistry; laboratory research experience for students; historical perspective; chemistry and the environment; laboratories using color to understand chemistry; electrochemistry laboratories; DIY instrumentation; organic semiconductors; orbitals; computer-based learning and computational chemistry; from the archives: paper chromatography.
Simple methods to prepare liquid air are described. In addition, ways to test the properties of liquid air and other liquefied gases are explored.
The solution to Chemical Mystery #11, which involves the Leidenfrost Effect, is presented.
What happens if you place metal that is glowing orange-hot into some water? Watch this video and find out!
Joshua Schrier has taken on a traditionally difficult task, teaching computational chemistry. To do this successfully, the student has to have programming skills, a solid foundation in the theory and background in the methods employed from classical physics to quantum methods. Thus the task is daunting and why so few have taken it on.
In a previous blog post, I shared a book Chemistry: A Very Short Introduction, by Dr. Peter Atkins. For my summer reading I wanted to get back to reading some chemistry non-fiction. I did, however, diverge from my original plan to read Eric Scerri's The Periodic Table: It's story and significance. Instead. "Four Laws That Drive the Universe" (with an alternative title of The Laws of Thermodynamics: A Very Short Introduction) became my next book as I so thoroughly enjoyed the writing style of Peter Atkins. The Kindle Version is only $6.15 and worth every penny in my opinion.
