WebpKa is the criterion used to determine the acidity of the molecule. Numerous parameters can determine the pKa values. We can calculate the pKa value from Ka, pH and titration curve. Web10 dec. 2024 · The degree of ionization is determined by the drug’s pKa and the pH of its environment. Weak acids and bases are 50% ionized and 50% unionized when the surrounding pH equals the drug’s pKa. At 2 pH units above or below the pKa of the drug, nearly 100% of the drug is ionized or unionized. Do ionized drugs cross membranes?
