Ionization behavior of aqueous short-chain carboxylic acids: a carbon-13 NMR study.
The 13C chemical shift of each carbon of aqueous acetic, propionic, and butyric acids has been measured as a function of pH or of added equivalents of base. A plot of chemical shifts for the carboxyl, alpha, and beta carbons as a function of pH is sigmoidal and yields pKa values that agree closely w...
