Feb 05, 2017· Answer Wiki. When the mixture is treated with a fairly strong solution of ammonia, silver chloride goes into solution by forming the complex ion [Ag (NH3)2]+, but lead chloride remains unaffected. AgCl (s) + 2NH3 (aq) = [Ag (NH3)2]+ (aq) + Cl- (aq) The unaffected lead chloride can be separated by filtration.
Sep 16, 2012· Rinse we filter the silver chloride from the solution, After the many water wash, we melt the silver chloride by addition of borax and carbon powder.

Jul 09, 2016· The progress of the removal of silver layer was observed at each pulsed voltage application. Results showed almost complete separation of the silver layer from the polycarbonate substrate by 25 shots of pulsed power with a stored energy of 35.3 J/pulse. In addition, discharge state was observed at each shot using a spectroscope and camera.
separation of silver ions as well as other metal ions in different samples. There are a number of reports of different types of chelating resins used in the separation, preconcentration or recovery of silver(I) ions and including functional groups; 2-mercaptobenzothiazole (14), thiol, purolite thiomethyl,
