Question

In the following sequence of recation, identify the compounds (A), (B), (C ) and (D):
`underset("Solution")Na_(2)CO_(3)overset(SO_(2))rarr (A) overset(Na_(2)CO_(3))rarr (B) overset(S)underset("Heat")rarr (C ) overset(AgNO_(3))rarr (D)`
A. `NaSO_(3).NaHSO_(3).Na_(2)s.Ag_(2)S`
B. `NaHSO_(3), Na_(2)SO_(3),Na_(2)S_(2)O_(3),Ag_(2)S`
C. `NaHSO_(3),Na_(2)SO_(4),Na_(2)S,Ag_(2)O`
D. `Na_(2)SO_(3),Na_(2)SO_(4),Na_(2)S_(2)O_(3),Ag`

Answer 1

Correct Answer - B
`Na_(2)CO_(3)+2SO_(2)+H_(2)O rarr underset((A))2NaHSO_(3)+CO_(2)`
`underset((A))(2NaHSO_(3))+Na_(2)CO_(3)rarr underset((B))(2Na_(2)SO_(3))+H_(2)O+CO_(2)`
`underset((B))(2Na_(2)SO_(3)+S overset("Heat")rarr underset((C ))(2Na_(2)S_(2)O_(3)`
`Na_(2)S_(2)O_(3)+AgNO_(3)rarr underset((D))(Ag_(2)S)+H_(2)SO_(4)`
