Isotope Effects in Deuterium Oxide Solution. I. Acid-Base Equilibria

It is suggested that the deuterium oxide-solvent isotope effect on aqueous acid dissociation constants arises principally from changes in zero-point energy associated in turn principally with changes in hydrogen bonding strength and number of dissociation. These considerations led to a simple quanti...

Zusammenfassung:It is suggested that the deuterium oxide-solvent isotope effect on aqueous acid dissociation constants arises principally from changes in zero-point energy associated in turn principally with changes in hydrogen bonding strength and number of dissociation. These considerations led to a simple quantitative method of estimating the isotope effect on acid-base equlibrium constants; this shows good agreement with experiment. (auth)
