Could you please help me.
When water is electrolyzed, two gases ar produced. As indicated in the chemical equation, twice the volume of one gas is produced compared to the other.
a) Which gas is produced in larger quantities? Explain
* I think it's hydrogen, but i am not sure why we need more hydrogen.
b)How could you test the gases to confirm your choice?
Thanks in advance.
