Question

What do oxidation reactions produce during the electrolysis of water?

Answer 1

Hydrogen gas, oxygen gas and water

4H2O (l) ---> 2H2O (l) + O2 (g) + 2H2 (g)

Answer 2

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:  $2H_2O+2e^-\rightarrow H_2+2OH^-$

At anode:  $2OH^-\rightarrow \frac{1}{2}O_2+H_2O+2e^-$

Overall reaction: $H_2O\rightarrow H_2+\frac{1}{2}O_2$

Oxidation reaction occurs at anode.

Hence, oxidation reaction produces oxygen and water molecule during electrolysis of water.
