Brønsted acids. The hydrogen ion H+ never exists on its own in a condensed phase, as it is always solvated to a certain extent. The high negative value of H0 in SbF5/HSO3F mixtures indicates that the solvation of the hydrogen ion is much weaker in this solvent system than in water.
Brønsted acids. The hydrogen ion H+ is never isolated in a condensed state, as it is always partially surrounded by solvent molecules to some degree. The high negative value of H0 in SbF5/HSO3F mixtures suggests that the solvation of the hydrogen ion is much weaker in this solvent system than in water.
