Electrolysis at high vs low voltages

Dec 16 2015Recently I've been trying out some electrolysis just to observe the results (and catch the occasional bit of hydrogen ) and I'm hoping to start learning much more about chemistry in general as at the moment I don't really know much about this When I decided to first do the experiment the only power source I had access to (that didn't provide a deadly current that is) was an old 30v 333mA Get price
