The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers). In the oxidation number change method the underlying principle is that the gain in the oxidation number (number of electrons) in one reactant must be equal to the loss in the oxidation number of the other reactant. Periodic Table of the Elements. La méthode du changement des nombres d’oxydation est une manière facile et simple d’équilibrer les équations d’oxydoréduction. Le processus est décrit ci-dessous.
