Why do we store silver chloride in a dark coloured bottle?
उत्तर
Silver chloride is a white solid. However, it is very senstive to sun light and decomposes in the presence of light to form silver (grey in colour) and chlorine.
`2"AgCl"("s") overset ("Sun light")(->) underset ("Grey")(2"Ag"("s")) + "Cl"_2("g")`
In order to avoid action by sun light, it is kept in a coloured bottle.
