But Robin, that's exactly the point. Unless you reduce the potassium ions to metal, at least temporarily, you will achieve no concentration of potassium ions at the cathode any higher than that of the whole of the electrolyte. Otherwise, as far as I can see, no manipulation of voltage,

Hi, Could someone tell me generally, which parameters affect the creation of potassium metal at the cathode of an electrolytic cell that uses a potassium carbonate electrolyte, and how to maximize it's production? Regards, Robin van Spaandonk All SPAM goes in the trash unread.
