For the generation of oxygen gas, hydrogen peroxide is generally used and by means of a catalyst, the peroxide is decomposed into two compounds: Liquid water and oxygen gas. The reaction is as follows:
Word equation
Hydrogen peroxide --->Water + Oxygen
Formula equation
[tex]2H_2O_2(aq)\rightarrow^{}2H_2(l)+O_2(g)[/tex]
It is important to note that the reaction needs a catalyst.
