Photochemistry: Silver Still Images Silver nitrate solution is poured into a dish containing a piece of filter paper. When sodium chloride solution is added, the paper becomes coated with a layer of solid silver chloride. The paper is moved to another dish, and a key is placed on top of it. When the paper is exposed to the light from a burning magnesium ribbon, the paper darkens due to photodecomposition of the silver chloride, which produces silver metal. Removing the key reveals its image on the paper. You can get at large JPEG versions of the images by means of the following links. 0 1 2 3 4 5 6 7 8 9 10 11 Back to the topic
