Pure silver is not sensitive to light, several silver *compounds* such as silver chloride and silver carbonate ARE. I've left batches of EIS on a sunny windowsill in clear glass for 5 years and they did not change at all. The batches that were not well sealed against air eventually oxidized and turned yellow, some of that yellow plated onto the glass. Hydrogen Peroxide destroys that particular form of silver oxide. There are 5 different forms of silver oxide possible, one of which is made by exposure to Hydrogen Peroxide. Take a black electrode and soak it in H2O2...it will become silver dust white very quickly. Leave it there for many hours and it will turn black again. Ode
