Procedure
This example illustrates the preparation of the silver coating solutionthat is used in Examples 4 and 5. 3 ml of a sodium tartrate solution (1 g tartaric acid disodium salt dihydrate (obtained from Aldrich) dissolved in20 ml distilled water) was added to 3 ml of a silver nitrate solution (10 gsilver nitrate dissolved in 10 ml distilled water) at 22° C. A whiteprecipitate of silver tartrate formed rapidly. Concentrated ammonium hydroxide, 28% ammonia (obtained from EM Science), was added dropwise to the solution until the silver tartrate dissolved completely to give a clear solution of ammonical silver tartarate with a pH of approximately 12.
