Q. The solubility of silver bromide in hypo solution due to the formation of
A) $\left\lbrack Ag\left( S_{2}O_{3} \right)_{2} \right\rbrack^{3 -}$
B) $Ag_{2}SO_{3}$
C) $\left\lbrack Ag\left( S_{2}O_{3} \right) \right\rbrack^{-}$
D) $Ag_{2}S_{2}O_{3}$
Explanation
(a)
The solubility of silver bromide in hypo solution due to the formation of $Na_{3}Ag\left( S_{2}O_{3} \right)_{2}.$
$AgBr + 2Na_{2}S_{2}O_{3}\ \longrightarrow Na_{3}Ag\left( S_{2}O_{3} \right)_{2} + 2NaBr$
