WebJul 14, 2015 · Bisphenol B (≥98%) and bisphenol E (≥98%) were obtained from TCI (Zwijndrecht, Belgium). Chemical structures, octanol-water partition coefficients (log K ow) and pKa values of the analyzed compounds are shown in Table 1. Individual stock solutions of each analyte (ca 1 mg mL –1) and a mixture of them were prepared in methanol. … WebCompare the pKa's. The pKa of the acid is near 5, and the pKa of the ammonium is near 9. The ammonium holds the proton more tightly than does the acid. The proton stays on the nitrogen. Amino acids are zwitterionic. A zwitterion is a compound that has no overall charge but that has charge separation within it. sigil of baphomet medallion
