Sulphonitronic acid

Occasionally the resulting acid solution is violet in colour, due to the presence of the unstable sulphonitronic acid (p. 251), and it then readily decomposes with effervescence of nitrie oxide. [Pg.153]

More recently this theory has been modified by the introduction of another intermediate product, namely the violet or blue sulphonitronic acid (see p. 251) which is supposed to precede the formation of the nitrosylsulphuric acid. The series of changes is then represented as follows ... [Pg.154]

The nitrososulphonie acid then reacts with a second molecule of nitrous acid, producing the purple sulphonitronic acid. As stated earlier, the composition of this acid is uncertain, but assuming the formula H2SN06, the equation for the reaction is... [Pg.154]

Sulphonitronic Acid or Purple Acid. —For a considerable time... [Pg.251]

A blue compound, apparently analogous to sulphonitronic acid (p. 251), is formed on the addition of mercury to a solution of nitrosylselenic acid in selenic acid monohydrate,5 or by reducing a solution of sodium nitrite in concentrated selenic acid by means of mercury. The presence of copper selenate facilitates the reaction. The selenonitronie acid is very readily oxidised and appears to be stable only in the presence of concentrated selenic acid. [Pg.341]
