The fixing of photographic plate film involves dissolution of unexposed silver bromide in hypo solution according to the equation that follows. AgBr(s)+2S2O2−3(eq)⇌Ag(S2O3)3−2(aq)+Br−(aq). If the molar solubility of AgBrin a 0.1 M hypo solution assuming its complete dissociation, is 4.3×10−x. Then find the value of x. Ksp of AgBr=4.5×10−13 Kf of Ag(S2O3)3−2=2.0×1013

1.	The fixing of photographic plate film involves dissolution of unexposed silver bromide in hypo solution according to the equation that follows. AgBr(s)+2S2O2−3(eq)⇌Ag(S2O3)3−2(aq)+Br−(aq). If the molar solubility of AgBrin a 0.1 M hypo solution assuming its complete dissociation, is 4.3×10−x. Then find the value of x. Ksp of AgBr=4.5×10−13 Kf of Ag(S2O3)3−2=2.0×1013
Answer» The fixing of photographic plate film involves dissolution of unexposed silver bromide in hypo solution according to the equation that follows. $A g B r (s) + 2 S_{2} O_{3}^{2 -} (e q) ⇌ A g (S_{2} O_{3})_{2}^{3 -} (a q) + B r^{-} (a q)$ . If the molar solubility of $A g B r$ in a 0.1 M hypo solution assuming its complete dissociation, is $4.3 \times 10^{- x}$ . Then find the value of $x$ . $K_{s p}$ of $A g B r = 4.5 \times 10^{- 13}$ $K_{f}$ of $A g (S_{2} O_{3})_{2}^{3 -} = 2.0 \times 10^{13}$
