In the following reaction sequence in aqueous solution, the species X,Y and Z respectively, are S _ 2 O _ 3 ^ 2 - Ag ^ + → X array ll Clear Solution array Ag ^ + → Y array ll White Precipitate array Withtime → Z array

Correct answer: A. [Ag ( S _ 2 O _ 3 ) _ 2 ] ^ 3 - , A g _ 2 S _ 2 O _ 3 , A g _ 2 S So, X, Y and Z are [Ag ( S _ 2 O _ 3 ) _ 2 ] ^ 3 - , A g _ 2 S _ 2 O _ 3 and A g _ 2 S respectively.

In the following reaction sequence in aqueous solution, the species

\text{X,}\text{Y}

and

\text{Z}

respectively, are

{S}_{2} {O}_{3}^{2 -} \overset{{\text{Ag}}^{+}}{→} \text{X}

\begin{array}{ll}\text{Clear} \\ \text{Solution}\end{array}

\overset{{\text{Ag}}^{+}}{→} \text{Y}

\begin{array}{ll}\text{White} \\ \text{Precipitate}\end{array}

\overset{\text{With}\text{time}}{→} \text{Z}

\begin{array}{ll}\text{Black} \\ \text{Precipitate}\end{array}

In the following reaction sequence in aqueous solution, the species X,Y and Z respectively, are S _ 2 O _ 3 ^ 2 - Ag ^

Options

A ${\left[Ag{\left({S}_{2}{O}_{3}\right)}_{2}\right]}^{3 -}, A{g}_{2}{S}_{2}{O}_{3}, A{g}_{2}S$
B ${\left[Ag{\left({S}_{2}{O}_{3}\right)}_{3}\right]}^{5 -}, A{g}_{2}S{O}_{3}, A{g}_{2}S$
C ${\left[Ag{\left(S{O}_{3}\right)}_{2}\right]}^{3 -}, A{g}_{2}{S}_{2}{O}_{3}, Ag$
D ${\left[Ag{\left(S{O}_{3}\right)}_{3}\right]}^{3 -}, A{g}_{2}S{O}_{4}, AgS$

Correct answer

A. ${\left[Ag{\left({S}_{2}{O}_{3}\right)}_{2}\right]}^{3 -}, A{g}_{2}{S}_{2}{O}_{3}, A{g}_{2}S$

Step-by-step solution

So,

X, Y

and

Z

are

{\left[Ag{\left({S}_{2}{O}_{3}\right)}_{2}\right]}^{3 -}, A{g}_{2}{S}_{2}{O}_{3}

and

A{g}_{2}S

respectively.
