The colour of the solution/precipitate obtained in the elemental analy

1.	The colour of the solution/precipitate obtained in the elemental analysis of an organic compound and the molecule/ion responsible for the colour are given below. Choose the incorrectly matched pair:
Answer» Prussian blue - `Fe_(4)[Fe(CN)_(6)]_(3).xH_(2)O` Black - PbS Violet colour - `[Fe(CN)_(5)NOS]^(4-)` Yellow - `(NH_(4))_(2)MoO_(4)` Solution :During the detection of P, the yellow PPT. obtained are due to `(NH_(4))_(3)PO_(4).12 MoO_(3)` (amm. Phosphomolybdate) and not due to `(NH_(4))_(2)MoO_(4)` (AMMONIUM molybdate). Thus, OPTION (e) is incorrect.
