Thanks for the clarification Ian.  You're the last clause of your 
statement:, "The manner of
creating ions by electrolysis is well researched and straight
forward, if not fully understood." ,  certainly applies to me.

 My comments to excerpts from your last post:

Ian:
"The manner of
creating ions by electrolysis is well researched and straight
forward, if not fully understood.
One would need to add protons to create a positive charge, which
would create a different element? Hydrogen ions (protons) have a
positive charge and are unlikely to combine with silver (there
are no silver hydrides). They are more likely to be reduced at
the cathode as hydrogen gas."

JOH:   I am suggesting not that the proton enters the nucleus of a silver 
atom to create a new element, but that it may be somehow associated---is 
that vague enough?---with the metallic Ag cluster.  Some of the hydrogen 
bubbles off at the electrode; some stays in solution as ionized water, 
balancing the pair of oxygen atoms.  Isn't pH the log of the number of free 
protons in the solution?   If the electrolysis current took an extra 
electron rather than donating on it would leave a proton.  Could some of 
them be contributing to the plus charge on/around(?) the silver cluster?

Ian:
"Silver Colloid particles are agrigates of either single silver
ions (simple ions) creating complex ions, or simple ions and
metallic atoms which will have a charge lower than the former.
Monoatomic ions are reactive because of their size, multiatomic
ions are able to accept more electrons per particle."


JOH:  What is the difference between a "complex silver ion" and a metallic 
silver colloid particle?  Or, what is the difference between  multiatomic 
ions---and a colloid?   If multiatomic ions are able to accept more 
electrons than a bit of metal, doesn't that make them more reactive?  Is 
there a difference between a multiatomic silver ion and a charged metallic 
silver particle?  Are we making some of both?

Most everyone agrees that a silver salt, most certainly highly ionized, is 
more reactive that a silver colloidal particle.  Is that so?

I think the question I have when boiled down is:

 if a single-atom "ion" is a "colloid", then what distinguishes it from a 
 "dissolved" atom "in solution"?



Thanks for your continuing instruction.  Please be patient with my 
questions, they arise more from intuition than technical knowledge.

And yes, I remain confused.

> HI everyone,

Hi,

Solution:
A homogenous mixture that remains mixed indefinitely.
Particle size... 0.01 to 1 nm
Will not filter out.
Will not reflect light (no Tyndal)

Colloid:
Heterogeneous mixture.
Remain dispersed by molecular motion (Brownian)
Particle size...1 to 1000 nm
Reflects light.

Ion:
(Physics and chemistry)
Atom, radical, molecule or aggregate that has lost or gained one
or more electrons.
(Biology and medicine)
The dissolved part of a solution (solute) which exists as charged
atoms or molecules.

There is no other way to create a positive charge other than
removing electrons that I know of.

Pitty he does not speak *colloid science*.
Silver Colloid particles are agrigates of either single silver
ions (simple ions) creating complex ions, or simple ions and
metallic atoms which will have a charge lower than the former.
Monoatomic ions are reactive because of their size, multiatomic
ions are able to accept more electrons per particle.

Whilst an electron has a particular charge, the energy required
to remove or gain one is different in each element, and the
conductivity is therefore different also. The energy required to
remove a second electron is much higher than to remove the
first... an so on.

There is no need to complicate things James. The manner of
creating ions by electrolysis is well researched and straight
forward, if not fully understood.
One would need to add protons to create a positive charge, which
would create a different element? Hydrogen ions (protons) have a
positive charge and are unlikely to combine with silver (there
are no silver hydrides). They are more likely to be reduced at
the cathode as hydrogen gas.

BTW, the zeta potential of a colloid is a measurement of the
electrostatic repulsion between the charged particles and their
Stern layers (neutralising layer of water molecules which travel
with the particle) and the diffused layer, and derives its value
from the charge on the particle, and is measured chiefly by
measuring the particles mobility.

Confused?
