I have been exercising some EIS over the past few days. I started out with a solution that had a conductivity of about 15 uS.
I added a very small amount of ascorbic acid. The solution turned amber brown, then went to grey. However, when I held it up to sunlight, it was more amber, but under the kitchen light it was grey. I then added some H2O2 and didn't think it was going to do anything, but the next day the solution was clear, with a good Tyndale effect. Conductivity is up to 25 uS. I then added some more ascorbic acid, and once again ended up with a grey solution. Add more H2O2 and after a while it clears back up. At this point the conductivity of the solution was about 75 uS. Once again I add some ascorbic acid. This time there wasn't much of a reaction. I added a little more, and after some time the solution turned to a light grey. Add more H2O2 and after a while it goes clear again. Conductivity is now up to 115 uS. Added more ascorbic acid and nothing happened. Added more and finally the reaction started. Let it sit for a few hours, and once again the solution is slightly grey. Add more H2O2 and after a while it goes clear again. Conductivity is up to 185 uS. Questions... What is going on? Have I worn this solution out, or is it still good for something? Is the increase in conductivity due to the addition of the ascorbic acid? Or am I chemically making a higher concentration? Is this similar to what goes on inside the body? Is this of any use to anyone? It was a fun experiment, but I am not sure if it has value. I have to confess that I am having too much fun. Tom
