Conclusions
-
1.
Solutions of potassium, rubidium, cesium, and tetrabutylammonium perchlorate in anhydrous perchloric acid were investigated by the PMR method. A linear dependence of the chemical shift of the proton in the weak-field direction on the molar concentration of perchlorate was detected. An analogous dependence exists in solutions of (C4H9)4NClO4-HClO4 in chloroform.

2.
HClO4 molecules form the anion H(ClO4) s−2 with perchlorates through a hydrogen bond. Evidently the dissociation of the biperchlorate anion in solution is negligible.
