Diphenylamine may be used as a wet chemical test for the presence of the nitrate ion. In this test, a solution of diphenylamine and ammonium chloride in sulfuric acid is used. In the presence of nitrates, diphenylamine is oxidized, giving a blue coloration.
Diphenylamine dissolves well in many common organic solvents, and is moderately soluble in water. [6] It is used mainly for its antioxidant properties. Diphenylamine is widely used as an industrial antioxidant , dye mordant and reagent and is also employed in agriculture as a fungicide and antihelmintic .
The aptly named paraffin test is also referred to as the diphenylamine test, dermal nitrate test and the Gonzalez test. This test consisted of coating a suspect's hands with paraffin wax , allowing it to solidify and peeling it away before adding a diphenylamine / sulfuric acid reagent.
N-(1-Naphthyl)ethylenediamine dihydrochloride is widely used in the quantitative analysis of nitrate and nitrite in water samples by colorimetry. It readily undergoes a diazonium coupling reaction in the presence of nitrite to give a strongly colored azo compound .
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The Griess test is an analytical chemistry test which detects the presence of nitrite ion in solution. One of its most important uses is the determination of nitrite in drinking water . The Griess diazotization reaction, on which the Griess reagent relies, was first described in 1858 by Peter Griess .
