Question

electrolysis of water​

Answer 1

electrotysis of water gives

H2O ------H2 + O2

H2 at cathode

O2 at anode

Answer 2

Electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current. The reaction has a standard potential of -1.23 V, meaning of ideally requires a potential difference of 1.23 V to split water.
