Okay so I made up a strong solution of ascorbic acid with pleny of sodium hydroxide, much stronger in each case then one would use for development, gathering up so of my many failed processing attempts and dumping them in the jar the silver developers and eventually is removed from the film.
Until I'm left with clear acetate/base, a very dark grey opaque solution.
Running it through a paper filter, barely any of the solution gets caught in the filter, so it is dissolved.
Im assuming if I evaporated the solution and use enough methylated spirits to redissolve the ascorbic acid, I can filter that off to remove the ascorbic acid, then redissolve in water, in which the silver shouldnt be able to dissolve without the ascorbic acid.. at least I think.
What form is the silver in the solution?
I want to experiment with this until I get my next order of chemicals in which will include bromide and nitric acid.
putting a little does clear a dark potassium permanganate solution clearer, and sort of a yellow dull colour, so im guessing its still metallic silver.. back to halides in the permanganate... i wonder if this can be of use to me
