Vedclass · Answer

(B) The brown ring test is used to detect the presence of nitrate ions $(NO_3^-)$. When $NO_3^-$ reacts with $FeSO_4$ in the presence of concentrated $H_2SO_4$,it forms a brown-colored complex. The reaction is: $Fe^{2+} + NO_3^- + 4H^+ 	o Fe^{3+} + NO + 2H_2O$. Then,$Fe^{2+} + NO + 5H_2O 	o [Fe(H_2O)_5NO]^{2+}$. The final complex formed is $[Fe(H_2O)_5NO]SO_4$,which is known as nitroso ferrous sulfate,responsible for the brown ring.

Nitrate is confirmed by the ring test. The brown color of the ring is due to the formation of:
