Versuchsvorschrift

This example illustrates the preparation of the silver coating solution that is used in Examples 5 and 6. Three (3) ml of a sodium tartrate solution (tartaric acid disodium salt dehydrate, obtained from Aldrich) dissolved in 20 ml distilled water) was added to 3 ml of a silver nitrate solution (silver nitrate dissolved in 10 ml distilled water) at 22° C. A white precipitate 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 ammoniacal silver tartarate with a pH of approximately 12.
