WebFor question 1, the correct answer is C - 83.3%. The Henderson-Hasselbalch equation is used to calculate the ratio of the ionized to unionized form of a weak acid or weak base in a solution. In this case, we have a weak acid with a pKa of 6.0 and a pH of 5.3. Using the Henderson-Hasselbalch equation for an acid, we get: WebThis fifth of a series of articles on intravenous admixture preparation considerations represents an introduction on pH considerations, which is presented in two parts, pH basics and applications, covering pH Considerations - Basics (In part 5 of this series): Basics of pH, pKa and Dissociation Constants, pH and Solubility, pH and Stability; and pH …
