    A substance that contains hydrogenand dissociates in solution to give hydrogenions :HA⇌H+ +A-More accurately,the hydrogen ion is solvated(a hydroxonium ion):HA +H2O⇌H3O++A-Strong acids are completely dissociated inwater. Examples are sulfuric ...[繼續閱讀]

    Having a tendency to release a pro-ton or to accept an electron pair from adonor. In aqueous solutions the pH is a mea-sure of the acidity,i.e.an acidic solution isone in which the concentration of H3O+ ex-ceeds that in pure water at the same tempera-ture...[繼續閱讀]

    A hydrogen atom in amolecule that enters into a dissociation equi-librium when the molecule is dissolved in asolvent. For example,in ethanoic acid(CH3COOH) the acidic hydrogen is the oneon the carboxyl group,-COOH分子溶解在溶劑中時進入解離平衡的分子中氫原子。 例如乙酸(CH3CO...[繼續閱讀]
