`underset("imparts violet colour to flame")((T)) overset("Compound (U)+conc. "H_(2)SO_(4))to underset("Red gas")((V))overset(NaOH+AgNO_(3))tounderset("Red ppt.")((W))overset(NH_(3)" soln.")to(X)`
`(W) overset("dil. KCl")to (Y)` white ppt
`(U) underset(Delta)overset(NaoH)to (Z)` gas (gives white fumes with HCl)
Identify (T) to (Z).

A

`T=KMnO_(4),U=HCl,V=Cl_(2),W=HgI_92),X=Hg(NH_(2))NO_(3),Y=Hg_(2)Cl_(2),Z=N_(2)`

B

`T=K_(2)Cr_(2)O_(7),U=NH_(4)Cl,V=CrO_(2)Cl_(2),W=Ag_(2)CrO_(4),X=[Ag(NH_(3))_(2)]^(+),Y=AgCl,Z=NH_(3)`

C

`T=K_(2)CrO_(4),U=KCl,V=CrO_(2)Cl_(2),W=HgI_(2),X=Na_(2)CrO_(4),Y=BaCO_(3),Z=NH_(4)Cl`

D

`T=K_(2)MnO_(4),U=NaCl,V=CrO_(3),W=AgNO_(2),X=(NH_(4))_(2)CrO_(4),Y=CaCO_(3),Z=SO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`underset(("Red ppt"))(Ag_(2)CrO_(4)(w)darrNH_(3))"solution"[Ag(NH_(3))_(2)]^(+)`
`underset(("Red ppt"))(Ag_(2)CrO_(4))overset("dil HCl")(rarr)AgCl`
`NH_(4)Clunderset(Delta)overset("NaOH")(rarr)underset((Z))(NH_(3))`
