Which one makes hydrogen
Hi all

I am trying to clear this up in my own mind as i have found different information on the good old net. Which one makes the hydrogen a possitive prob or negitive prob i am sure it is the negitiveCrazy Please help!

When the water splits into ions, as it does when you dissolve the electrolyte in it, it splits into a H+ ion (positive charge) and an OH- ion (negative charge). Positive ions will be drawn to the negative electrode, and vice versa. So the H+ ions will go to the negative electrode, where the electrolysis will neutralise the charges and release H2 molecules.

RE: Which one makes hydrogen
Both probes are required to separate H2 and O2 molecules from water. The actual splitting is caused by electrons passing through the liquid which disrupts the bonding of the two types of molecule in the liquid. Actual separation of the two is much as as Paulusgnome describes. Hydrogen with a net positive charge is attracted to the negative probe, O2 with a net negative charge to the positive probe.

To answer your question, in electrolysis, both probes play an active part in both hydrogen and oxygen production. Polarisation of the probes aids in separation of the two gases.

Hope this helps.

p.s. Probes can be any shape. Plate, rod, etc, etc.

RE: Which one makes hydrogen
Pardon my ignorance but just clear things up. Is it better to have more negative electrodes in the cell than positive?

That's a matter of some conjecture. Some would say definitely yes, others that it makes little overall difference. Case of suck-and-see what works best for you.
