Potassium permanganate volcano near end of eruption
The potassium permanganate volcano is a classic chemistry demonstration that produces smoke, colored flames and sparks, a glow resembling lava, and colored ash. This type of chemical volcano captivates students while illustrating principles of redox reactions, oxidation, exothermic reactions, the effect of surface area on reaction rate, decomposition reactions, and […]

Bath bombs dissolve in an endothermic reaction
An endothermic reaction is a chemical reaction that absorbs heat from its environment. Like any chemical reaction, an endothermic reaction requires activation energy to proceed. Then, it continues to absorb energy. Such reactions feel cold. In contrast, exothermic reactions release more heat than they absorb and feel hot. Not all […]
