Abstract It has been a long pursuit to discriminate the ionic roles of mono- and di-valent salt solutions in modulating the hydrogen bonding network and solution properties. We attended this issue by examining the effect of concentrated YX2 (Y Mg, Ca, Sr; X Cl, Br) solvation on O:H O bonds transition from the mode of ordinary water to hydration in terms of the number fraction fYX2(C) and the segmental O:H O bond phonon stiffness shift Δω(C) with C being the solute concentration. The invariant dfY(C) / dC at C ≤
