Vedclass · Answer

(C) The brown ring test is a common laboratory test used to detect the presence of nitrate ions $(NO_3^-)$ in a solution. When $FeSO_4$ is added to a solution containing nitrate ions,followed by the careful addition of concentrated $H_2SO_4$ along the sides of the test tube,a brown ring is formed at the junction of the two layers. The reaction involves the reduction of nitrate ions to nitric oxide $(NO)$. The $NO$ then reacts with the hydrated ferrous sulfate $[Fe(H_2O)_6]SO_4$ to form a nitroso-ferrous sulfate complex,$[Fe(H_2O)_5(NO)]SO_4$,which is brown in color. Therefore,$NO$ is the species responsible for the formation of the brown ring.
