Question

Is it possible to produce hydrogen by decomposition of water by means of heat,electricity or light?how?give chemical reaction

Answer 1

It is possible by electricity(Electrolysis)

Answer 2

Hey there,


● Answer-
Yes. Electrolysis of water yields hydrogen.

● Explanation -
- Electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current.

- Reaction occurs is -
2H2O ---> 2H2 + O2
- Oxygen is liberated at anode and hydrogen is released at cathode.
- This reaction usually requires a potential difference of 1.23 V.

Hope it helps...
