Q.In Lassaigne's test for the detection of nitrogen, the sodium fusion extract is boiled with $FeSO_4$ and then acidified with concentrated $H_2SO_4$ . The Prussian blue color is due to the formation of:

Fe_4[Fe(CN)_6]_3

Na_4[Fe(CN)_6]

Fe_3[Fe(CN)_6]_4

Fe(SCN)_3

The correct solution involves applying the fundamental concept to derive the final value step by step...
