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.

Collaboration among Chemical Educators
The February 2019 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: microplastics and environmental chemistry; examining outreach practices; investigating acid–base chemistry; using Arduino to experiment with carbon dioxide; innovative approaches to analytical chemistry; three-dimensional visualization and tactile learning; understanding Lewis structures; synthesis laboratories; exploring physical chemistry; from the archives: celebrating the International Year of the Periodic Table.
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.
