Re: Producing CS with different settings (findings)

Esstee,

a) One rule of thumb is to avoid dipping bellow 9v so as to preserve the integrity of the Eletrolytic process.

...

c) I've found the presence of metallic taste to be in direct relation to oxidation. However, when I took increased measures to avoid oxidation I discovered that the solution would have very little taste even in higher than average concentrations 20+ppm.

The purpose of the batch I did was exactly to enter in the so called "forbidden" zone, below 9 volts, to see what happens.

By looking the collor (picture, plastic bottle with diameter around 10 cm), I can say that the silver concentration was smaller than my previous batches.
 

With 3 large anodes (large wet surface) against just one small surface cathode the oxidation on anodes was the smallest I ever had. As expected the single cathode became black more than in other setups. In addition I cleaned the rodes a number of times, removing even the very small layer of oxidization.

I could not identify any problem by allowing the voltage to drops below 9 volts. As the voltage continues to drop after cross the 9 volts psicological barrier, my conclusion is that the electrolysis happens normally, at least until around 5.8 volts.

If the taste comes from the oxidization, the only acceptable explanation is that it comes from the cathode. Maybe yes, but maybe comes from the ionic charge as I read a number of times at internet.

So far, nothing is conclusive.
