Simple chemical tests are described that can indicate the presence of certain metals in coins. A wide variety of chemical concepts are involved. The experiments described are a natural fit for the 2019 National Chemistry Week theme of "Marvelous Metals!"
This post describes some simple experiments using various coins and neodymium magnets that connect to the 2019 National Chemistry Week theme of Marvelous Metals!
Hi everyone! My name is Clarissa Sorensen-Unruh, and I am a new Lead Contributor/Blogger for the Two-Year College component of ChemEd Xchange. I am beyond thrilled, though, to join ChemEd Xchange and learn more about your interests on this platform. I am hoping you, as the audience, will help guide the topics I write about so that we can focus our discussions to interests both you and I share.
Have you ever seen the liquid nitrogen cloud? Do you wonder how the cloud forms when hot water is thrown onto liquid nitrogen? This post explores the liquid nitrogen cloud and possible explanations for its formation.
The solution to "Chemical Mystery #16: A Red, White, and Blue Chemistry Trick for You!" is presented. How this experiment can be used as a springboard to carry out a simple quantitative analysis of salt solubility is also discussed.
Watch this video and see if you can figure out how red, white, and blue colors can all be made from the same chemical solution!
The solution to Chemical Mystery #15: The Leaky Cup is shown here.
In honor of the International Year of the Periodic Table: A familiarity with the chemistry of some of the elements more commonly encountered in everyday life is a valuable learning experience for all students. Sulfur is the fourth in this series of elements to be discussed as part of the Element of the Month program. #IYPT
Time for a new chemical mystery! Watch the video below and see if you can use your chemical knowledge to figure out how this experiment is done.
This is a fantastic way to celebrate the birthday of the periodic table of elements! There is still time to get involved and create an element to include when it is put together at a spectacular event October 19, on the campus of Grand Valley State University in Allendale, MI. Extended Deadline!
