Firstly, the conclusion that, "High quality colloids contain a high percentage of silver particles [ by this the authors mean uncharged particles of silver metal ]. Ideally, a silver colloid would contain no ions." does not address the fact that ions are probably the active ingredient of CS.
Ivan: Apparantly they provide no supporting evidence for their conclusion. Of course, if the object of the exercise is to produce a high quality colloid in the literal sense of the word, then the authors may be correct in their conclusions. However if the object is to produce a CS which is most effective in its antiseptic action, then the conclusions drawn are irrelevant, unless a colloid, in its literal sense, fulfils such an outcome. Ivan: Again, there appears to be no supporting evidence for these conclusions. The authors also mention that silver ions will ionise water, ie, break it apart into H+ and OH- components (the first time I have ever heard of this) "The negative charge of the hydroxyl ions counters the positive charge of the silver ions and maintains a solution of whose net charge is zero." which completely ignores the positive charge of the H+ ions which must be equal in number to the OH- hydroxyl ions from which they split. Ivan: Perhaps the conceptual error here is to emphasize CONCENTRATION and not ACTIVITY which is the true measure of how and to what extent species interact. For example, it is not necessary to split apart additional water molecules into hydrogen and hydroxyl ions in order to change the activity of either ionic species, and, therefore, affect pH. This phenomenon occurs because it IS possible the change the environment around water molecules which can increase its polarity. I believe that the HVAC process which uses an arc to produce CS may generate many extremely small, charged CS particles that increase the polarization of nearby water molecules which "exposes" more of the positive end of the molecule which effectively raises the activity of H+, thus lowering pH.
