Conclusions

  1. 1.

    Based on the literature data, we calculated the concentrations of the H5O2 + and H3O+ ions, and also of the H3O+·HSO4 − ion pairs (or H2SO4·H2O hydrates), in aqueous H2SO4 solutions (ranging from 2.04 to 100% H2SO4).

  2. 2.

    It is postulated that the H3O+ ions can exist only in solutions that contain more than 76% H2SO4, where less than two water molecules correspond to each proton.
