Introduction ~~~~~~~~~~~~ This is a continuation of a previous experiment to find ways to make cs ions visible. Salt was added to the dw to make silver chloride. The first experiment used too much. The second was a bit better, but the white cloud is very faint and difficult to see. A time stamp was added to each observation. Experiment #4 ~~~~~~~~~~~~~ Added just enough dw to wet 1 inch of electrodes, about 200ml. Added lots of salt until the solution turned slightly cloudy. Applied 335 uA current. Sun Jul 27, 2003, 09:03:54 am 13.25e-3V 335uA The cell resistance is very low. Nothing seems to be happening at either electrode. I will let it run for a while. Decided to increase the current to 3.28mA Sun Jul 27, 2003, 09:08:23 am 63.7e-3 3.294mA Sun Jul 27, 2003, 09:18:08 am 1.44V 3.265mA Sun Jul 27, 2003, 09:24:25 am 1.4548V 3.267mA Sun Jul 27, 2003, 09:30:03 am 1.4571V 3.309mA A few bubbles rising. Anode has small bubbles along side of rods. Cathode has bubbles underneath the bottom of each loop. Sun Jul 27, 2003, 09:40:56 am 1.4636V 3.333 mA Bubbles have stopped forming at cathode. Sun Jul 27, 2003, 10:06:24 am 1.4917V 3.330mA A few bigger bubbles appearing at anode. Anode rods look very black under water. Nothing else seems to be happening. I will rotate the rods 90 degrees and record the voltage. Sun Jul 27, 2003, 10:09:43 am 1.2V 3.3mA The voltage dropped then very quickly rose. Terminated the experiment. The anode rods now have a hard black film on the portion that was under water. The previous film that was on the cathode is removed over the same distance. Experiment #5 ~~~~~~~~~~~~~ Sun Jul 27, 2003, 10:20:31 am I filled the glass to cover the bottom inch of rods as before. I put one shake of salt in my palm. This made a circle about 1/4" in diameter when spread out to a single layer. I added it to the dw and stirred. Used the "W' electrode for the anode. Sun Jul 27, 2003, 10:22:03 am 1.56V 3.25mA Sun Jul 27, 2003, 10:22:54 am 1.70V 3.28mA Sun Jul 27, 2003, 10:23:37 am 1.86V 3.30mA Thin white streamers are falling from the bottom of the anode. The entire rods are covered with a fuzzy white cloud. It is not uniform. Sun Jul 27, 2003, 10:29:06 am 1.95V 3.29mA A very faint wavefront is crossing the space between the electrodes. It is about 1/3 the way across. The edge is difficult to see. You have to backlight the solution and look sideways between the electrodes. It is a bit further across at the bottom than the top. Sun Jul 27, 2003, 10:39:02 am 1.95V 3.27mA The cloud continues across. It is past the halfway mark. It helps to put a piece of dark paper behind the glass and illuminate from the side. The bottom of the cathode rods are turning white. Sun Jul 27, 2003, 10:41:59 am 1.98V 3.30mA The top of the cloud has turned into something looking like a thunderhead. It has reached all the way across to the cathode rods. Sun Jul 27, 2003, 10:43:31 am 1.98V 3.30mA The bottom of the cloud is almost all the way across. Sun Jul 27, 2003, 10:46:20 am 1.99V 3.30mA The cloud has reached the other side of the glass. The left side of the glass is filling up with silver chloride. The right side is filling up with a faint milky color. With not much else happening, the experiment was terminated. Conclusion: Salt shows a similar effect as anthocyanin. The silver chloride forms a very faint white color that is just as hard to see. However, there is no deep bronze color coming from the cathode as before, and we can trace the silver ions from the anode all the way across to the cathode. This experiment is a bit messy, and it will take a while to clean the glass and electrodes. Best Regards, Mike Monett -- The silver-list is a moderated forum for discussion of colloidal silver.
