Nitrate test
From Wikipedia, the free encyclopedia
A nitrate test is a chemical test used to determine the presence of nitrate ion in solution.
A common nitrate test 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.[1] Note that the presence of nitrite ions will interfere with this test.[2]
