Company Silver
how is silver used in a camera and film company?
what chemical reactions are used that are involved with the silver?
***the possible reactions are:
decomposition
synthesis
double replacement
single replacement
combustion
thanks so much!
I’m fairly sure it is one of the “replacement” reactions- and I think it is double replacement. I am not a chemist, but in the photographic process, after “developing” the film, one must “wash” it- which suggests the removal of the second compound created in the reaction. This is also true of photographic papers- you have to put them in a “bath” after toning.
Sorry- it has been years since I was in a darkroom- everything is digital now:) I recommend doing a quick google search on darkroom chemistry.
