The reaction between peroxide and potassium iodide
There are all kinds of chemical changes in the world. Now the reaction between hydrogen peroxide ($H_ {2} O_ {2} $) and potassium iodide ($KI $) is a chemical phenomenon that is fascinating to explore.
Hydrogen peroxide is an oxidizing colorless liquid. Potassium iodide is a white crystal that is easily soluble in water. When the two meet, it is like starting a wonderful journey of chemical change.
When hydrogen peroxide and potassium iodide meet in a suitable environment, the iodine ions ($I ^ - $) in potassium iodide can act as a catalyst to accelerate the decomposition of hydrogen peroxide. The chemical equation of the reaction is as follows: $2H_ {2} O_ {2}\ stackrel {KI }{=\!=\! =} 2H_ {2} O + O_ {2}\ uparrow $.
In this reaction, hydrogen peroxide decomposes to produce water ($H_ {2} O $) and oxygen ($O_ {2} $). Looking at it, it can be seen that there are bubbles escaping, which is a characteristic of oxygen generation. And because the reaction is exothermic, the temperature of the system may rise.
As for potassium iodide, although it participates in the reaction process, the reaction ends, and its chemical properties and quality remain unchanged. It can still be regarded as a catalyst. The wonder of this reaction lies in the fact that simple things achieve the wonders of chemical change, the generation of water and oxygen, and the decomposition and transformation of hydrogen peroxide catalyzed by potassium iodide are indeed interesting phenomena in the chemical world.
