True enough. There are many ways that the stability of a colloidal suspension can be disturbed, most however involve a chemical reaction of some description or other. > The aggregaton with ascorbic acid is not a reaction in the chemical sense, > it is simply an aggragation.

Silver ions are anything other than inert. Ag+ is quite a strong oxidiser. CS is composed, in the main, of silver ions. Whilst elemental silver is a stable metal (noble) and does not react spontaneously with many substances (ascorbic acid will oxidise metallic silver), this is not the case with silver ions. > Marshall Ivan. -- The silver-list is a moderated forum for discussion of colloidal silver.
