Hi Kevin, You may be right, most of the current sag may well be in the build up of charge in the electrode/water double layer. And without in depth study I am not in a position to argue the toss. But it undoubtedly true that the current passes through zero at each polarity change ...how much this slows the reaction I cannot say.
Here is a nice site with some info ...also on various rotating electrodes. http://www.bath.ac.uk/~chsacf/java/electrochemistry/elec/l6html/cvac.h tm Regards Ivan. > -----Original Message----- > From: Kevin Nolan [mailto:[email protected]] > Sent: Monday, 21 January 2002 2:42 a.m. > To: [email protected] > Subject: Re: CS>Polarity Switch Experiment > > > Ivan - inertial effects are completely negligible in any > electrolysis setup. > The relaxation time (roughly a dividing line between > resistive and inertial > response) for ions in water is I think of the order of 10^-13 > seconds or so. > Even taking the electrolysis setup - container plus DW plus > electrodes, as a > capacitor, the electrical system relaxation time would be > much less than a > microsecond.
