Question

Why hydogen gas is formed during the process of elctrolysis of the water is double to the oxygen?

Answer 1

Because there are two atoms of Hydrogen and one atom of Oxygen in a water molecule

FORMULAE --

H2O

Answer 2

at the anode, the reaction is

${{4OH}^{-}- 4e}$= 4OH

4OH=2H2O+O2

since 4 electrons are needed...therefore to balance it,

4 electrons are needed at cathode

${{4H}^{+} + 4e= 4H}$

4H= 2H2

so h2 is double of o2
