Silver chloride decompose

Silver chloride is an usual chemical compound which was used in photography. Silver chloride is a white substance, it could be prepared through silver nitrate to react with sodium chloride solution. In this reaction, silver chloride would precipitate under the vessel.

                                         Silver chloride precipitates under the vessel

Silver chloride is very sensitive to UV light(high energy radiations), because the bonds between silver ions and chlorine ions are weak so when silver chloride is under exposure with light it would decompose quickly.

                              Use filter paper to separate silver chloride from the solusion


                                             Applied silver chloride over the filter paper
                                           Put one dollar NT on the paper to be a cover,
                                           and use UV light to react with silver chloride.
                                          Silver chloride turn into dark after UV exposure
