Abstract Stable complexes are formed between 8-quinolinol-5-sulfonic acid and praseodymium (III) and neodymium (III). There is no conclusive evidence for the existence, in solution, of complexes between that acid and praseodymium and neodymium in higher oxidation states than three. Dry solid potassium nitrosyl disulfonate is stable indefinitely, but the moist solid decomposes quite rapidly. In acid solution, nitrosyl disulfonate ion undergoes autocatalytic decomposition. In the investigation of this decomposition it was discovered that the reaction between nitrosyl disulfonate and hydroxylamine monosulfonate ions is catalyzed by iron. The investigation of these two reactions, and particularly the kinetics of the latter reaction are described.
