Respuesta :
hydrogen gas, oxygen gas and water
4H2O (l) ---> 2H2O (l) + O2 (g) + 2H2 (g)
4H2O (l) ---> 2H2O (l) + O2 (g) + 2H2 (g)
Answer : Oxidation reaction produces oxygen and water molecule during electrolysis of water.
Explanation:
Electrolysis : It is a type of process in which the chemical decomposition produced by passing an electric current through the solution that containing the ions.
Electrolysis of water : It is basically the decomposition of water into oxygen and hydrogen gas through a process of electric current.
Oxidation reaction is defined as the reaction in which a substance looses its electron to attain stability.
The chemical reactions during electrolysis of water are:
At cathode: [tex]2H_2O+2e^-\rightarrow H_2+2OH^-[/tex]
At anode: [tex]2OH^-\rightarrow \frac{1}{2}O_2+H_2O+2e^-[/tex]
Overall reaction: [tex]H_2O\rightarrow H_2+\frac{1}{2}O_2[/tex]
Oxidation reaction occurs at anode.
Hence, oxidation reaction produces oxygen and water molecule during electrolysis of water.
