Question

Addition of sodium thiosulphate solution to a solution of silver nitrate gives X as white precipitate, insoluble in water but soluble in excess thiosulphate solution to give Y. On boiling in water, Y gives Z . X, Y and Z respectively are (A) Ag2S2O3, Na3[Ag(S2O3)2], Ag2S (B) Ag2SO4, Na[Ag(S2O3)2], Ag2S2 (C) Ag2S2O3, Na5[Ag(S2O3)3], AgS (D) Ag2SO3, Na3[Ag(S2O3)2], Ag2O

The sequence of reactions are <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/8e622843a77d3cabaee31dd107f19836-.png" /> Hence, X = Ag 2 S 2 O 3 Y = Na 3[ Ag ( S 2 O 3)2] Z= Ag 2 S

Q. Addition of sodium thiosulphate solution to a solution of silver nitrate gives $X$ as white precipitate, insoluble in water but soluble in excess thiosulphate solution to give $Y$ . On boiling in water, $Y$ gives $Z . X, Y$ and $Z$ respectively are

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

$A g_{2} S O_{4}, N a [A g (S_{2} O_{3})_{2}], A g_{2} S_{2}$

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

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

The sequence of reactions are

Hence, $X = A g_{2} S_{2} O_{3}$
$Y = N a_{3} [A g (S_{2} O_{3})_{2}] Z = A g_{2} S$
