I observe a red to blue color change when I rinse my bowl after eating frozen blueberries. Sounds like an acid-base reaction, doesn’t it? Well, read on to learn about the blueberry surprise!
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 author explains how she assigns roles for her students while completing laboratory work. The lab activity is designed to allow students to explore the use of indicators. It serves as an introduction to acids, bases and pH.
Did you figure out how the experiment in Chemical Mystery #14 was performed? The solution is presented here!
You can figure out how this Valentine's Day experiment was done...if you know your chemistry, that is!
Erica Jacobsen shares highlights from the February 2019 issue of the Journal of Chemical Education.
A few years ago, the faculty in our department at Slippery Rock University of Pennsylvania decided to switch to an atoms first approach to the General Chemistry course. We took advantage of this change to systematically redesign the first semester of the laboratory curriculum to be a true “laboratory course” that focuses on laboratory practices, techniques, and equipment rather than on chemical theory.
The solution to Chemical Mystery #13: Bye Bye Blue! is presented. This experiment is useful to demonstrate to students when discussing acid-base indicators, neutralization reactions, or the acidity of carbon dioxide when it dissolves in water.
A simple, but tricky experiment is displayed. Can you figure out how the trick was done?
