Nitric acid is made by the reaction of nitrogen dioxide with water. Normally, the nitric oxide produced by the reaction is re-oxidized by the oxygen in air to produce additional nitrogen dioxide. Adding Sulfuric Acid to a nitrate salt and heating the mixture with an oil bath can make almost pure nitric acid.
