It will prodce O2 as the oxidation reaction as oxidation of O changes from -2 to 0 !!

So your answer is third one ; O2(g)

Answer: Oxidation reaction produces oxygen and water molecule during electrolysis of water.

Explanation:

Electrolysis of water 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.
