Answer:
Silver bromide is used in white photography as it involves photo decomposition reaction in which silver bromide is broken down into silver metal and bromine gas evaporates.....The silver metal left enables us to see photos....
Chips are puffed with nitrogen gas to prevent RANCIDITY.....
Hope it helps....
