Don't you have some work you have to do Roger?

<< Ivan had suggested using H2O2 to reduce the size of silver "clumps"
as a purifying effect of poor product and the discussion of silver being
a catalyst sparked an idea in my mind, as we were at the time looking
for a simple home test. Give the whole list credit if you wish!
I later suggested the "baggy" test, after determining it was qualitative,
not quantitative and easily upset by dirty glassware! I expect the time
of formation rate and density of bubbles/sq. in. are good indicators of
particle size! You can note on a dime that it is a very slow process vs.
the rapidity with silver "sludge" - clearly a surface area dependency!
Finer particles = faster bubble formation and with more particles there
will be more bubble sites/sq. in.!
It is quite clear to me, that if no bubbles are formed with an ionic form of
Cs (I employ all measures to avoid the formation of crystals) yet they are
formed with a obviously poor running setup where a dense cloud is
allowed to form and stringers start (an indication of growth of crystals)
then it is a valid test to detect elemental silver. I would expect in the
HVAC arc sintering process that atoms or larger particles are formed
and thus the high bubble rate I found!
Fred: If larger silver particles are the cause for the catalytic reduction of
H2O2 (which, according to you, are prima face evidence of a poor brew), how
do you explain that HVAC CS remains clear and no CS drops out of suspension
over extended periods of time (probably never as far as I can tell). From all
the discussion on the 'list' with regard to CS color and particle size, it
seems pretty clear that the consensus opinion (Are YOU going to criticize me
for relying on consensus opinion?) was that a clear sol indicates acceptably
small silver particles. So you can't have it both ways; which statement is
wrong and which is correct?
I said Atoms, which sound pretty small to me! Would a suspension of atoms
have a long "hang" life? It is accepted by others that silver ions
cluster in groups
of 6 or more and thus your atom would actually be smaller!
As further verification, of the effect, you can take "ionic" Cs and let it
evaporate on a glass surface, leaving a brown residue. I believe from
chemistry that what is left must be of the metallic form, not ionic, a
deposit of fine crystals. It foams rapidly when
H2O2 is placed on it, indicating a high surface to mass area!
Fred: Let me see if I've got this straight: You just made up a brew of silver
IONS from your LVDC process. There are no anions present, mind you, just
silver cations, but THAT doesn't seem to bother anyone on this list but me.
Then you evaporate all the water and magically ALL the ionic silver turns
into metallic silver. Question: Just WHAT exactly provided all the electrons
to turn ionic silver into metallic silver? Seems to me, such are reaction
(if, in fact, it DID occur) would produce a helluva lot of heat, or would be
so rapid as to explode. Any sign of a rise in temperature, or explosion,
Fred?
No explosion Roger, I believe God took the free electrons from my highly
statically charged body and contributed them to the silver ions, as the
vapor produced by evaporation rose to touch my body, forming a conducting
path! Try it, you will see it works every time!
Your turn,
It appears one (or both) of us are out of our sphere of expertise here! Any
"molecular techie helpers" out there to help Roger know an ions life
cycle?:)
