Question

The passage represents a qualitative analysis flow diagram:
(I) [Yellow ppt.] $\xleftarrow{	ext{K}_2	ext{CrO}_4}$ (A) [Gives blue colour 
to the flame] $\xrightarrow{\Delta}$ (B) [Brown Gas] $\xrightarrow{	ext{Gas 
(H), Very low temp.}}$ (C) [Blue colour liquid] 
$\xrightarrow{	ext{H}_2	ext{O}}$ (D)
(A) $\xrightarrow{	ext{H}_2	ext{S}}$ (F) [Black ppt.] $\xrightarrow{	ext{dil.
HNO}_3}$ (G) [Vapour] + (H) [Gas]
(H) $\xrightarrow{	ext{FeSO}_4 + 	ext{H}_2	ext{SO}_4}$ (E) [Complex compound]

Correct answer: B. Compound (I) is PbCrO4. It is soluble in NaOH (forming [Pb(OH)4]2-) and in HNO3, but insoluble in CH3COOH.
