Question

(e) The ratio of hydrogen and oxygen formed at the
cathode and anode is 2:1 by volume give reason​

Answer 1

Explanation:

Because Water's chemical representation is H₂O. That means, each water molecule has 2 hydrogen atoms & 1 oxygen atom. When electricity passes through water, the H₂O molecule breaks up into 2 Hydrogen & 1 oxygen atoms. So their ratio is 2 : 1.

Answer 2

Answer:

when electricity passes through water the H2O molecule break s up into two hydrogen and 1 oxygen atmos .So there ratio is 2:1 .As we see therefore the ratio of hydrogen to oxygen is 2:1 by volume when formed at canthode and anode
