Hi, I am trying to perform a rather complex experiment involving the electrolysis of water. But, I need more info. about it. I was somewhat able to find the answers to a few in your Archives, but I'm not sure how each of these factors would work together in my experiment. First, I need to know how much electricity it takes to split water. I know the basic chemical equation, but I don't know how much electricity is actually needed. I don't know how this is measured, I suppose in joules per gram or joules per mole or something like that. Also, how does the amount of electricity needed vary with pressure on the water (especially high pressure)? with content of the electrolyte? Also, which common household items or items you could buy at a hardware store or something could be used in electrolysis, besides NaCl? would baking soda work? And are there any substances that can act as catalysts rather than products? NaCl seems to be split as well when used in electrolysis. Thank you very much for taking the time to answer any of these questions!
