The rapid reduction of NpO 2  2+  ions to NpO 2  +  by U(IV) ions in an aqueous nitric acid solution has been studied and, in many ways, is similar in character to the same reaction in HClO 4 . The major difference is that in HNO 3  the reaction proceeds  via  two parallel routes. The first is  via  the hydrolysed UOH 3+  ion, as in the reaction in HClO 4  and the second is  via  the non-hydrolysed U 4+  ion. These parallel routes lead to the observed order of reaction with respect to H +  ions being reduced from −1 in HClO 4  to −0.7 in HNO 3 . After accounting for the reaction mechanism the rate equation is described by:
