The question of whether water can form hydrogen peroxide should be answered by thermodynamics (see C&EN, June 13, 2022, page 3). If a reaction is possible (spontaneous), then the change in the Gibbs ...

Breaking something rarely sparks joy—unless you’re activating a glow stick. Just bend the plastic baton until you hear a snap, and behold, you have a radiant wand to illuminate your way. Whether ...

Some chemical reactions change temperature, change color, produce a gas, or make a solid from two liquids. Try this reaction and see what it does! Pour 1 tablespoon of hydrogen peroxide into a cup.

Hydrogen peroxide is widely used in everyday life, from disinfectants and medical sterilization to environmental cleanup and ...

Hydrogen peroxide decomposes on its own into water and oxygen gas. This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate, and the bubbles are full of oxygen ...

THE formation of a well-defined red complex between hydrogen peroxide and methæmoglobin or metmyoglobin is well established 1–3. Keilin and Hartree found that the formation requires one molecule of ...

The reaction of hydrogen peroxide with potassium iodide is demonstrated in a tall cylinder. Saturated potassium iodide is added to a mixture of soap, glycerin, water, and hydrogen peroxide. Oxygen and ...

Hydrogen peroxide is an ingredient in many bleaches, dyes, cleansers, antiseptics, and disinfectants. It has many potential uses, such as for skin care and oral hygiene. However, there are also safety ...

Hydrogen peroxide is a common, affordable household cleaning and disinfecting product. In an unopened bottle, hydrogen peroxide can last for around 3 years. However, once you open the container, it ...

One of the more dangerous medical myths I frequently see in the ER is the widespread belief by patients that copious amounts of hydrogen peroxide should be used to clean cuts and scrapes of any size.
