Dissolving silver metal with ammonium thiosulfate
So I have been researching ways to remove silver nitrate from skin I have a couple stains on my skin
Silver dissolves in sodium cyanide well known
Can it be removed with potassium ferricyanide as this has a cyinide group
Also can I remove the stain with ammonium thiosulfate
Supposidly used for desolving gold

I would try thiosulfate long before CN or ferricyanide! Could use Na or NH4 thiosulfate. Both probably work. Thiosulfate will complex with Ag and make
something soluble.

In silver halide photography thiosulphate is used to remove silver halide via a complex leaving the grains of silver untouched. From memory to remove
the silver with thiosulphate it had to be oxidised first to a halide.

The stains will wear off by themselves. The outer layers of your skin are constantly being sloughed off and replaced, and the stained ones will be
gone in a week or so. No sense trying to scrub it off with cyanide when all you have to do is wait.
Please remember: "Filtrate" is not a verb.

This is your best option, unless you have a job interview or a major event within the next 5 days, I'd just wait.
