Hydrogen ions are always associated with another molecule in solution
In aqueous solutions, hydrogen ions (protons) do not exist as bare isolated particles; rather, they are invariably hydrated and associated with water molecules or other chemical species, forming hydronium or other complex ionic structures.
The retrieved papers consistently describe hydrogen ions in aqueous solution as hydronium ions, part of hydration shells, forming ion pairs, or participating in water-mediated proton transfer networks. There are no papers contradicting the chemical reality that free protons associate with solvent molecules in solution.
