WebAn acid is a chemical that dissociates in an aqueous solution, producing the hydrogen ion H + (a proton), according to Arrhenius’s original molecular definition: HA ⇌ A– + H+. H2O … WebApparent ionization constants of water in aqueous organic mixtures and acid dissociation constants of protonated cosolvents in aqueous solution. Earl M. Woolley; and ; Loren G. Hepler; Cite this: ... Ionization constants for water and for very weak organic acids in aqueous organic mixtures. Journal of Solution Chemistry 1974, 3 (2) , 119-126. WebThe theoretical estimation of the dissociation constant, or pKa, of weak acids continues to be a challenging field. Here, we show that ab initio Car–Parrinello molecular dynamics simulations in conjunction with metadynamics calculations of the free-energy profile of the dissociation reaction provide reasonable estimates of the pKa value.
