WebFeb 4, 2024 · pKa and pKb are related by the simple relation: pKa + pKb = 14 What Is pI? Another important point is pI. This is the isoelectric point. It is the pH at which a protein (or another molecule) is electrically neutral (has no net electrical charge). Cite this Article WebThe best way to answer this question is to look up the pKbs for these compounds. The smaller the pKb, the stronger the base. So, for pyrrole, pyridine, and methyl amine the pKbs are 13.6, 8.75, and 3.38, respectively. This means the rank-order of basicity is methyl amine > pyridine > pyrrole. 6K views Pratik Sarkar
