Question

Gases formed when electricity is passed through distilled water
(1) oxygen
(2) hydrogen
(3) both oxygen and hydrogen
(4) no reaction

Answer 1

Answer:

hydrogen

Explanation:

when electric current is passed through water,Electrolysis of water occurs ,which is the decomposition of water(H2O) into hydrogen gas (H2) and oxygen (02).The reaction ideally requires a potential difference of 1.2 volts in order for the water molecules to split up .

Answer 2

Required answer :-

Gases formed when electricity is passed through distilled water: both oxygen and hydrogen.

Therefore, option 3 is correct.
