Nitric acid reacts with most metals, but the details depend on the concentration of the acid and the nature of the metal. Dilute nitric acid behaves as a typical acid in its reaction with most metals. Magnesium, manganese, and zinc liberate H 2: Mg + 2 HNO 3 → Mg(NO 3) 2 + H 2 Mn + 2 HNO 3 → Mn(NO 3) 2 + H 2 Zn + 2 HNO 3 → Zn(NO 3) 2 + H 2
It is a yellow gas that is commonly encountered as a component of aqua regia, a mixture of 3 parts concentrated hydrochloric acid and 1 part of concentrated nitric acid. It is a strong electrophile and oxidizing agent. It is sometimes called Tilden's reagent, after William A. Tilden, who was the first to produce it as a pure compound. [1]
Although it is the salt formed by neutralizing guanidine with nitric acid, guanidine nitrate is produced industrially by the reaction of dicyandiamide (or calcium salt) and ammonium nitrate. [2] It has been used as a monopropellant in the Jetex engine for model airplanes. It is attractive because it has a high gas output and low flame temperature.
The oxidation of copper by nitric acid is a complex reaction forming various nitrogen oxides of varying stability which depends on the concentration of the nitric acid, presence of oxygen, and other factors. The unstable species further react to form nitrogen dioxide which is then purified and condensed to form dinitrogen tetroxide.
It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2]
The compound is a salt with separated hydroxyammonium and nitrate ions. [2] Hydroxylammonium nitrate is unstable because it contains both a reducing agent (hydroxylammonium cation) and an oxidizer (), [3] the situation being analogous to ammonium nitrate.

Silver cyanate reacts with nitric acid to form silver nitrate, carbon dioxide, and ammonium nitrate. [ 4 ] AgNCO + 2 HNO 3 + H 2 O → AgNO 3 + CO 2 + NH 4 NO 3
