An incorporation of the acid-base theory of Lewis [1] and Arrhenius [2] to the recent development of the structure and hydrogen bond(HB,or O:H-O)relaxation dynamics of liquid water [3] has resulted in clarification of water interaction with acid-base-salt in solutions in terms of quantum fragilation,compression,and polarization.Phonon spectrometrics confirms that the H+(→)H+ point breaker,O:(→):O compressor,and the X-and Y+ polarizers resolve the performance of the HB networks.The H+?H+ anti-HB between the H3O+ and one of its four H2O neighbors “pinholes” regularly the HB network,making the HX acid solution corrosive,dilutive,and skin-stress destructive.The O:(→):O super-HB between the HO-and one of its H2O neighbors “compresses” the neighboring O:H nonbonds but elongates the H-O bonds,making the YOH base solution greasy,skin-stress constructive,and ejecting heat at hydrating.The X-and Y+ polarizers align,cluster,and stretch their surrounding HBs,forming the hydration shells that regulate the skin-stress and protein solubility of salt solutions.These unprecedented quantum switchers shall be critical to drug-cell,solute-solvent,solution-protein interactions.Observations evidence the essentiality of bond relaxation consideration [4].
