Hi Roger, I am not entirely clear what happens to CS in the digestive tract, I have trouble finding reliable information...more work to be done. I am still of the view that only Ag ions can pass into the blood stream.
The solubility constant of AgCl (Ksp) = 1.8 x 10^-10 When concentration [Ag+] = [Cl-] then [Ag] dissolved = 1.34 x 10^-5 M Ksp = [Ag+][Cl-] 10.8ppm CS contains 1.0 x 10^-5 M so that is at the limit of solubility with an equivalent amount of Cl- . Higher concentrations of Cl- (product) gives higher concentration of the reactant (AgCl), known as the common ion effect. The concentration of [Cl-] in HCl at pH2 is 1 x 10^-2 M [Ag-] = 1.8 x 10^-10 / 1.0 x 10^-2 = 1.8 x 10^-8 M So only 1/500th to 1/1000th of our initial 10ppm CS will remain dissolved, the rest is passed on as insoluble AgCl, although higher temperatures increase the solubility and I am as yet unsure on the effect of the H+ ions and other enzymes, proteins and so on. Also if the concentration of Cl- anions drops in the duodenum the solubility of the Ag+ ions will increase. What do you make of it?
