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!
I am already planning for my trip to Illinois in July to attend ChemEd 2019! Let me tell you why I want to attend.
Observe both an exothermic and an endothermic reaction/process as I use a modified propane torch in the video demonstration.
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?
Based upon reader comments on previously published, Chemical Mystery #12, I experimented and found that this demonstration is easy to pull off with relatively inexpensive and easy to find materials.
