The brown ring test is used for testing the presence of nitrate(NO3-) radical, in nitric acid and in nitrate salts. At first you take a test tube. In that test tube you take nitric acid soln. or any nitrate salt soln. add freshly prepared ferrous sulfate soln, incline the t.t. then add conc. H2SO4 slowly through the wall of the t.t. A brown ring will be formed at the junction of the two solutions. The composition of the brown ring: [Fe(H2O)5NO]SO4.
