--- Begin Message ---Hello Ken, Andrew and other paragons of CS, The Starved Electroded was discovered quite by accident while during experiments for constructing current density tables. Any good meters will be satisfactory, however I was using an RS model 174B LCD Digital Auto-ranging multimeter, a couple of RS model 803 LCD Digital Auto-ranging multimeters, a Simpson 260 multimeter and a Calectro model H3-361 multimeter. The RS 174B also measures temperature. The thing to do is get the electrode potential at 13.3% above the electron ionization potential. For the Ag atom the Potentials are ; Ag I 7.542v 13.3% over is 8.5v Ag II 21.4v 13.3% over is 23.8v ( in the range of 3 nine volt batteries) Ag III 35.9v 13.3% over is 40.7vI would select a current I wanted to run at,such as 3 ma ( in my case that would be 4.5ua/mm2 of wetted electrode area) and keep the current at 3ma or under during the run. Start the run and let the current build up to the limit you have selected for the experiment. Begin increasing series resistence to the electrodes ,alway keeping the current at 3ma (any current you select). As the conductivity of the CS becomes higher the current will try to rise and you need to keep increasing the series resistance. Monitor the electrode voltage and current all the time and tabulate it as you go. If you don`t have time to stay with it don`t bother to try, as it needs constant monitoring. Every 5 minutes stir the water CCW and record the current before and after stirring. Normally after each stir the current will drop as the CS is dispersed from the vicinity of the electrodes.I use four sets of electrodes, located around the edge of the vessel. My stirring is in the middle of the CS solution. Your tabulation (charting) will look like a series of sawteeth. As the solution becomes saturated and the electrode voltage reaches the target potential a strange thing will happen. Each time you stir the CS the current will INCREASE (instead of decreasing) and you will find that the tabulated sawteeth will be reversed from the previous sawteeth. Each time you stir the saturated CS the solution is increasing (adding to) the energy of the circuit and the current rises momentarily. Once the the sawtooth reversals are evident the current will no longer increase, it becomes self regulating. The CS ppm will level off and remain steady. I usually let it run another 30 minutes to ensure complete saturation. The solution is now saturated, will not accept any more ions. The ionic potential is now 13.3% above the ionization potential. It is maintaining a status quo, the ionic potential is balancing the external potential applied to the electrodes. Under this condition the ionic potential will cause the ppm to begin to rise when external power is removed. The energy stored in the CS being used to continue the CS making process. This was also discovered not too long ago by another of our experimenters. :-) Sometimes I would stop and let the solution set for many hours and start it again to see what would happen. It always started where I had left off. The self ppm rise will only happen after the solution is saturated and at high energy.
