Question

Explain what is meant by electrolysis of water.Write the electrode reaction and explain them.

Answer 1

Electrolysis of water is its decomposition to give hydrogen and oxygen gases due to the passage of an electric current.

 

2H2O + electrical energy - O2 + 2H2

 

Answer 2

Hello friend

___________________________


⚫ Electrolysis of water

Electrolysis of water is the decomposition of water into oxygen and Hydrogen gas due to an electric current being passed through acidified water.

Cathode reaction ::

2H2O + 2e negative=>H2 + 2OH negative

Anode reaction:::


2H2O => O2 + 4H positive + 4e negative


If is found that in the above activity that the volume of gas formed near the anode.Hydrogen gas is formed near the cathode and oxygen gas near the anode.

From this,it is clear that electrolysis of water has taken place and it's constituent elements have been released.


Thanks...
