Balanced Equation For Hydrogen Peroxide
On the balance reaction formula of hydrogen peroxide
The chemical principle of the world, in the reaction of hydrogen peroxide, the balance formula is related to many changes.
Hydrogen peroxide, its formula is $H_ {2} O_ {2} $, often shows its unique properties in chemical reactions. If it is decomposed, oxygen and water can be produced. The equation of its balance should be deduced from chemical principles.
$2H_ {2} O_ {2}\ stackrel {MnO_ {2 }}{=\!=\!=} 2H_ {2} O + O_ {2}\ uparrow $. In this case, due to the change of the valence state of oxygen in hydrogen peroxide, it is necessary to follow the conservation of gains and losses of electrons. In the reaction, part of the oxygen of hydrogen peroxide increases in price to oxygen, and part of the price decreases to oxygen in water. According to this reason, the balance coefficient is appropriate in order to conform to the law of chemical change.
And the reaction of hydrogen peroxide with some reducing agents also needs to be accurately balanced. Take its reaction with ferrous ions as an example, ferrous ions are oxidized to iron ions, and the oxygen in hydrogen peroxide decreases in price. After analyzing the electron transfer, the balancing formula can be obtained: $2Fe ^ {2 + } + H_ {2} O_ {2} + 2H ^ {+} = 2Fe ^ {3 + } + 2H_ {2} O $.
From this point of view, the balancing reaction formula of hydrogen peroxide can be accurately deduced according to different reaction situations and basic principles of chemistry, such as conservation of mass, conservation of gain and loss of electrons, etc., to illustrate its state in chemical changes.
