MDJH Posted August 15, 2007 Share Posted August 15, 2007 I remember reading about electrolysis of water before learning about it in chemistry class during the school year, and now I want to try it. First off, what is a safe electrolyte for it? Also, since the quantity of products is determined by the charge transferred, (as in the current and low long the current is flowing) then what effect other than determining whether or not electrolysis occurs does the voltage have? As in, if the charge transferred is the same in one case where the voltage is barely above the cell potential and another case where the voltage is much higher than the cell potential, since the energy transferred will be much higher, where does that extra energy go? Would it heat the solution? If I were to do water electrolysis using a 1.5 volt cell (I think water's cell potential is 1.23 volts) would the extra 0.27 volts not dissipated by the electrolysis overheat the cell? Also, would the size of the water container affect it? Link to comment Share on other sites More sharing options...
