3 A nitrate test is a chemical test used to determine the presence of nitrate ion in solution. A common nitrate test‚ known as the brown ring test[1] can be performed by adding iron(II) sulfate to the solution‚ then slowly adding concentrated sulfuric acid (NOT nitric acid‚ for obvious reasons) and watching for a brown ring on the test tube‚ which will indicate the presence of the nitrate ion.[2] Note that the presence of nitrite ions will interfere with this test.[3] The test follows several

of one or more compounds‚ is injected into the column and is carried through the stationary phase by atmospheric air‚ which acts as the mobile phase. The nonpolar coating of the stationary phase most strongly retains solutes of the same polarity. Organic compounds flowing out of the chromatography column are then detected by a chemical sensor that produces electrical responses proportional to the concentration of the compounds. The presence of such a chemical at the detector is seen as a peak on a
