In a message dated 00-04-12 07:58:11 EDT, you write: << #Thanks, I can buy that. Just not sure that a particular color always means the same thing. Perhaps coal is black because of its particle size [molecular crystal size?] and diamonds are clear because that size is different? Or would that be differing crystal configurations and lattice structures. You got it! [shapes and fits?] Presuming identical chemical/elemental makeup. Uh, the difficulty part strikes a bell :-) Another question If I'm getting many hydrogen bubbles on one side and some, but very few oxygen bubbles on the other and that pole turns black, what's going on? The ratio of hydrogen to oxygen is nowhere near 2 to 1 as would be expected.
Let's see if I can help. Anode(1): Ag(metal cluster which tends to separate at lattice weak points and/or areas of high surface free energy such as edges) -----> Ag(metal cluster with positive electrostatic charge)+ n(e-) Where n = 1 for clusters of tens of thousands of Ag atoms [THUS, THIS AGGREGATE DOES NOT, IN FACT, CANNOT, ACT AS A SILVER ION -- IT'S SIMPLY AN ELECTROSTATICALLY CHARGED SILVER PARTICAL] COMPETING REACTIONS: Anode(2): 2H2O -------> O2(gas) + 4H(pos ion) + 4e- Cathode: 4H(pos) + 4 e- --------> 2H2 (gas) Sum of Reactions Ag + 2H2O --> Ag(colloidal w/ superficial surface charge) + O2(gas) + 2H2(gas) The amount of H2(gas), and O2(gas) depends on the level of 'overvoltage' (beyond the theoretical minimum to produce O2 and H2 in the first place) which in turn is a function of the surface overvoltage required (certain electrodes are composed of metals and conductive materials that act as catalysts primarily because of their huge surface area which will greatly reduce overvoltage) AND the thickness of the boundary layer at the surface of the electrode (i.e. stirring, for example, will decrease the thickness of the boundary layer and thus lower overvoltage). There are other factors which could also lower overvoltage which I won't get into here. Hope this helps, Roger -- The silver-list is a moderated forum for discussion of colloidal silver.
