Is Chocolate Cake an Acid-Base Indicator? Testing a Student Claim
Josh Kenney | Mon, 02/28/2022 - 10:21
Recently, Josh Kenney took time from his regular scheduled chemistry curriculum to investigate a student's claim that chocolate cake was an acid-base indicator.
Q, K, ∆G and ∆G°: The Darlings of Thermodynamics
Joseph Lomax | Sun, 02/27/2022 - 19:55
In two connected ways, thermodynamics describes how both physical or chemical processes spontaneously trend towards equilibrium. This post is concerned with showing how free energy (ΔGrxn) changes as the reaction quotient (Q) changes as both trend towards the special condition, equilibrium, described by the constant K.

Radioactivity of Red-Orange Fiestaware
Melanie Harvey | Mon, 02/21/2022 - 19:50
Finding demos related to nuclear chemistry that are interesting, relevant, and manageable is challenging. Melanie Harvey is both a chemistry professor and a ceramic artist. Using Fiestaware to talk about the historical use of radioisotopes is one of her favorite demonstrations.
Expanding on Self-Inflating Balloons: Activities Involving Moles, Gas Laws, and Thermochemistry
Dean Campbell | Thu, 02/10/2022 - 08:42
Balloons that inflate using carbon dioxide produced from the reaction of citric acid and sodium hydrogen carbonate can be used to demonstrate a number of aspects of chemistry. Gas laws were used with the balloons to illustrate limiting reactants, molar mass of gases, and rockets. The endothermic reaction in the balloon was visualized with an infrared camera, and the Green Chemistry aspects of these balloons were considered.
