Warning: This is a collection of ideas gleaned from various conflicted sources and observations, and based on my own agglomeration of what might be going on. It's not necessarily "fact".
In fact, I get the distinct idea that 'no one' knows what the facts are.
Yellow indicates that some agglomeration of particles has happened.
Pale yellow at a given PPM says that very few agglomerated, deep yellow, that most have.
An agglomerated particle is one that has grown in its crystaline form.
In nature, crystals often form around a nucleus like ice around dust to make a snowflake.
Inpurities in the water can nucleate a crystal. I suspect that an undissolved silver oxide can as well.
Peroxide acts as a catalyst to break the crystals apart.
Peroxide will also dissolve the black oxide coating that appears on the electrode.
This leads me to believe that silver oxide can nucleate a silver crystal which can grow larger under the right wrong conditions and that peroxide scavenges the nucleus out just as it dissolves an oxide coating on the electrodes.
A pure yellow is most likely low in oxide content while a tea color or yellow/black indicates high oxide content in the crystals. [speculation]
Either way, peroxide busts them up till the particle size is small enough to stop displaying 'any' color...sometimes small enough to become invisible in visible frequencies of light.
Putting a few drop in an 'older' stabilized batch that's not yellow does nothing apparent except changing the quality of the TE.
Sometimes it will become finer and stronger. Sometimes it goes away completely. [see previous statement about invisible particles] I suppose it all depends on how much peroxide is added.
In very fresh CS, just a tiniest touch of peroxide will cause a violent reaction that makes it flash milky white with massive TE. I suspect that's a silver hydroxide stage. There is also a release of gas bubbles, not sure it that's hydrogen or oxygen, but it does form a little bit of an emulsion that contributes to the very strong TE which clears up a little bit over time without anything settling out.
Just a little more will make it flash milky brown with a massive TE. I suspect that's a silver oxide stage...again some emulsion effects.
Adding a little more will turn it clear again and just a little more, TE vanishes. I suspect that's a metallic formation stage with atomic cluster/crystals ranging from very small to invisibly small.
I suspect that very fresh CS sets up a different reaction chain with the radicals in the body and releases oxygen into the blood stream which gives [me, anyhow] a noticeable energy boost..a distinct feeling of "awakeness".
Several others concurr.
Since my toenail fugus was clearing up while I was using only very fresh CS on a daily basis, but slowly grew back [much slower than not using any CS] after I started using stored batches, I suspect that fresh CS is more bioavailable. Conclusion may be flawed somehow...I don't know.
Conductivity changes very little with the addition of Hydrogen Peroxide in small amounts, so hydrosol content probably doesn't change much or one dissolved conductive form shifts to another dissolved conductive form while metallic particulate 'mass' stays the same but the pieces get smaller.
[Incidently, I can't seem to find a non conflicted definition of a hydrosol. Now, I'm not a chemist and most of this stuff is way over my head, but I can generally tell when someone is going out of their way to say nothing while making the 'appearance' of saying something profound]
Regarding CS making: No one really 'knows' what is happening and everything is so dynamic that it's not likely that anyone ever will. [ie: EVERYTHING is ALWAYS happening, sometimes all at once. The question is, what's happening, how much ....right now?]
If you place an oxide blackened electrode into peroxide, it will clean it very fast.
If you LEAVE that electrode in there, it turns black again.
Very fresh CS has mostly ions that have not yet located their anions. It stands to reason that free ions and anions would contribute to condcutivity better than those hat have formed a bond with each other. Conductivity drop over time seems to confirm that idea.
Available anions are radical unstable hydroxls and unstable radical oxygen complexes..possibly monoatomic oxygen, hydrogen peroxide and ozone in varying trace amounts as well as the normal diatomic oxygen that has little effect on silver. [What the "probabilities" are, I don't know and have no way to find out]
The componants of CS are dissolved and undissolved silver oxides [2 to 5 possible forms], dissolved and undissolved silver hydroxides, free silver ions associated with water molecules as a "hydrosol" and metallic particles, all in varying proportions that all get broken down in the body systems to a great degree into ions...some of which get involved in a fulminating silver reaction stage that winds up making small metallic particles.
The body itself manufactures small amounts of hydrogen peroxide and has various other free radicals wandering around.
Since ionic silver just loves a negatively charged free radical..it could just be the ideal antioxident. [pure speculation]
[radical oxygen complexes carry a negative valence or charge, silver ions a positive one. "Normal" oxygen and silver are charge neutral. A Free Radical is more chemically reactive than most anions and may strip a silver ion from a weak unstable hydroxl bond]
PS I tried making a batch using [A LOT] of peroxide added to the water. I got huge silvery snowflakes and conductivity gain not exceeding 13 uS even after several days of run time. Very pretty, but that's all it was.
Revisited 2013: A couple of drops of H2O2 added to the batch water before starting will enhance the "colloidal" portion quite nicely...I'd not exceed 6 or 10 drops of 3% to the quart.
