A combination of differential phonon spectrometrics (DPS) and DFT calculations verified the essentiality of H+-H+ point fragilization and X
polarization dictating the surface stress of HX (X = Cl, Br, I) solutions. H+-H+ repulsion breaks the network regularly; X
polarization shortens and stiffens the H-O bonds but lengthens and softens the O:H nonbonds in its hydration shell. The X
- capability of hydrogen bond and surface stress transformation follows the order of I > Br > Cl. Observations provide fresh insight into the acid solvation network dynamics. DPS resolves solute capabilities of transforming the bonds and surface stress.
