Consider the following reaction :
`Na_(2)SO_(3) + S overset("Boiling")underset(H_(2)O) to X` (Colourless liquid) AgBr `overset("Excess")to Y` (Soluble complex)
`X + Cl_(2) + H_(2)O (l) overset("Boiling")underset(H_(2)O)to Z + HCl`
The (X), (Y) and (Z) are respectively

A

`Na_(2)S_(4)O_(6), [Ag(S_(2)O_(3))_(2)]^(2-), NaHSO_(4)`

B

`Na_(2)S_(2)O_(3), [Ag(S_(2)O_(3))_(2)]^(3-), NaHSO_(4)`

C

`Na_(2)S_(4)O_(6), [Ag(S_(2)O_(3))_(2)]^(3-), NaHSO_(4)`

D

`Na_(2)S_(3)O_(3), [Ag(S_(2)O_(3))_(2)]^(3-), Na_(2)SO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Na_(2)S_(2)O_(3) + S overset("Boiling")underset(H_(2)O)to Na_(2)S_(2)O_(3)[X]`
`AgBr + 2Na_(2)S_(2)O_(3) to underset("Soluble complex Y")(Na_(3)[Ag(S_(2)O_(3))_(2)]) + NaBr`
`Na_(2)S_(2)O_(3) + 4Cl_(2) + 5H_(2)O overset("Boiling")to 2NaHSO_(4) + 8HCl`
