The emission of the Auger electrons during the formation of the Mössbauer nucleus ^{57}Fe leads not only to the formation of multicharged ^{57}Fe^{n+} ion, but also to the appearance of the Auger blob, a cloud of several hundreds of ion-electron pairs (H_2O^{+}, e¯) in the solvent around the Fe ion. Fast radiation-chemical reactions therein determine the experimentally observable ratio of the yields of final chemically stable charged states of the Mössbauer ions (Fe^{3+} and Fe^{2+}). This ratio strongly depends on reaction rates constants between H_2O^{+}, e¯, and the solute S. We have shown that in contrast to radiation chemical data the reactivity of NO_{3}^{-} anions with quasi-free track electrons in frozen aqueous solutions exceeds those of H_{3}O^{+}, ClO_{4}^{-}, and HSO_{4}^{-} ions only by a factor of three instead of ≈ 100 which follows from the radiation chemical experiments.
