I am doing some experiments with alternative film chemistry and I am starting to get concerned about safety. One experiment involves converting a small amount of metallic silver to silver chloride and then soaking the film in an weak ammonia solution (< 10% ammonia hydroxide), to dissolve the silver chloride, additionally there may be small amounts of silver oxide and silver metal left on the film. I read somewhere that in experiments involving ammonia and silver compounds that the dangerous explosive silver nitride could be produced. Should I be worried about it? would I be producing it in dangerous quantities? or at all? There is probably only a few grams of silver on the entire film strip.
What are some sensible precautions I could take here?
