The "brown-ring" test is used as a toss for nitric acid er solutims of nitrates in the laboratory,
Med solution of freshly prepared ferrous sulphate a-miter is first added to an aqueous solution of a nitrate in a test-tube. A few drops of: concentrated sulphuric acid are then slowly pouri down the side of the test-tube. The ŝoid settles to the bottom of the tube and forms a' copárate layer of liquid. at the jubetion of the two layers, a brown ring will be formed.
