Is separating hydrogen and oxygen molecules possible? If so, how?
I believe that this is why my chemistry set experiment use muratic acid with one anode zinc and the other I can't recall. At ten, I wasn't using a high voltage.Might be worth noting that it is pretty expensive (energy-wise) to separate water into hydrogen and oxygen..... that is to say it costs more energy to separate them than one can reasonably expect to get back by burning one, the other or both.
On the other hand, separating hydrogen from hydrocarbons is a much less costly procedure, and is being done with membranes (Palladium, alloys, and now even some stainless steel alloys - experimentally) ... This technology is seen as having serious potential for hydrogen generation for use in fuel cells. This sort of thing is in its early stages, but is currently being used aboard some US Navy submarines for power generation.
