Dissolving silver bromide in a fixer solution
Not what you're looking for?
Solid silver bromide AgBr (s) is removed from the film by dissolving it in an aqueous "fixer" solution containing sodium thiosulfate, Na2S2O3 (aq). This reaction produces NaBr (aq) and Na3Ag(S2O3)2 (aq), which can be rinsed away from the film. A fixer solution is prepared by dissolving 120g Na2S2O3 in enough water to make 4.00 L of solution. What volume of fixer is required to dissolve 20.0g of solid silver bromide?
