Question

the ratio of hydrogen and oxygen formed at cathode and anode is 2 is to 1 by volume by the reason is should be​

Answer 1

Explanation:

Are u speaking about electrolysis of water

if yes then because in water hydogen and oxygen are combined in the ratio 2:1 by volume they will disscociate in the same ratio i.e 2 atoms of hydrogen combine with 1 atom of oxygen chemically

Answer 2

Answer:

because hydrogen have 1+ ions that not efficient for reaction with oxygen. O2 have atomic no 8 and they have 2- ion so they cannot satisfy the law of conservation of mass then , hydrogen take ions for reaction
