Text Solution

Verified by Experts

The correct Answer is:
C
`2CuSO_(4)+K_(4)[Fe(CN)_(6)]rarrunderset((Brown ppt))(Cu_(2)[Fe(CN)_(6))]+2K_(2)SO_(4)`
`2NaBr+3H_(2)SO_(4)rarr2NaHSO_(4)+underset ((Brown))(Br_(2))+SO_(2)+2H_(2)O`
`AgNO_(3)+KNO_(2)rarr underset(("White ppt."))(AgNO_(2))+KNO_(3)`
`CaS_(2)O_(3)+2HClrarrCaCl_(2)+SO_(2)+S+H_(2)O`
