WebNitrous acid is a weak acid, with an acid dissociation constant in dilute aqueous solution of pKa = 3.3, about 105 less than that of nitric acid. In its free acid state, it is unstable and decomposes easily, decomposing immediately into nitric oxide and nitric acid in water. Therefore, it is stored in the form of nitrous acid or nitrous acid ester.
