Correct answer is (a) [ As ( S 2 O 3)2]3-, Ag 2 S 2 O 3, Ag 2 S

Q. In the following reaction sequence in aqueous solution, the species X, Y and Z, respectively, are
$S_{2} O_{3}^{2 -} Ag X^{+} clear solution X Ag X^{+} White precipitate Y with time black precipitate Z$

$[A s (S_{2} O_{3})_{2}]^{3 -}, A g_{2} S_{2} O_{3}, A g_{2} S$

$[A g (S_{2} O_{3})_{3}]^{5 -}, A g_{2} S O_{3}, A g_{2} S$

$[A g (S O_{3})_{2}]^{3}, A g_{2} S_{2} O_{3}, A g$

$[A g (S O_{3})_{3}]^{3 -}, A g_{2} S O_{4}, A g$

Correct answer is (a) $[A s (S_{2} O_{3})_{2}]^{3 -}, A g_{2} S_{2} O_{3}, A g_{2} S$
