(C) The brown ring test is a common laboratory test used to detect the presence of the nitrate ion $(NO_3^-)$ in a solution. When a freshly prepared ferrous sulfate $(FeSO_4)$ solution is added to the nitrate solution,followed by the careful addition of concentrated sulfuric acid $(H_2SO_4)$ along the sides of the test tube,a brown ring is formed at the junction of the two layers. This brown ring is due to the formation of the complex $[Fe(H_2O)_5(NO)]SO_4$.
