I copied the following from a web site.  There has been a lot about chelated 
silver in our magazines and wanted to know how to make it if it can be made at 
home?  Has
anyone had any experience making Chelated Silver?  Does it have draw backs that 
our cs doesn't?

Chelated Silver™ is silver ions in solution. It is vastly different from the 
silver-based dietary supplement products known as colloidal silver, which is 
silver in suspension. In colloidal silver, finely divided particles of 
elemental silver are randomly floating in suspension in water and are not 
evenly dispersed. In CHELATED SILVER™, ions of pure, crystallized silver 
nitrate are chemically bonded to nonmetallic ions, and are therefore evenly 
dispersed throughout the solution. This bonding in solution considerably 
enhances Chelated Silver™'s antimicrobal action and persistance (killing power 
over time).

In colloidal suspensions, minute silver particles of elemental silver are 
suspended or randomly floating in water, typically at a level of 10-50 parts 
per million. Chelation occurs when a metal ion forms a heterocyclic bond with a 
bidentate ligand. Examples of bidentate ligands are carbonate and oxalate ions 
and ethylenediamine. As a general rule, five- or six-member lingands are 
favored. Chelated Silver™ ions are chemically bonded to nonmetallic ions and 
are evenly dispersed throughout the solution. This concentrated and uniform 
dispersal of Chelated Silver™ ions (typically at a level of 300 to 400 parts 
per million) throughout the solution considerably enhances their antimicrobial 
action, persistence and effectiveness.

Chelated Silver™ is highly effective in blocking the respiration of 
microorganisms causing them to expire. Additionally,  scientific testing is in 
progress to study the effectiveness of Chelated Silver™ in interdicting 
anaerobic bacteria (bacteria that exists in the absence of oxygen).
