Hi, Terry, My reference to the 0.1 M solution of silver nitrate was to give evidence that silver nitrate is a colorless solution, even at concentrations far beyond that used for medicinals. The American Chemical Society webpage illustrates a chemical lab experiment, not a clinical experiment.
If the 0.1 M solution is transparent and colorless, then a 0.1 millimolar solution (about 10 ppm Ag+) will surely be transparent and colorless too, don't you agree? Also, I did get a hold of Hill and Pillsbury's summary (chapter IX, pp 128-131.) They report: "Generalized argyria has been reported to have been produced by EVERY compound of silver in common clinical use at the present (1939) time, with the exception of silver oxide." (capitalization mine.) In their summary, Hill and Pillsbury also state about silver: "Transportation in the body occurs principally via the blood stream and to some extent via the lymphatics. A majority of investigators believe that it is transported in the form of chloride or albuminate." Silver albuminate could be formed by a reaction of blood serum (not blood cells) with silver ions in solution. Matthew
