WebFormula. Percent Ionized Formula. where x = -1 if acid drug or 1 if basic drug. Basic Rules. pKa is defined as the pH were a drug exists as 50% ionized and 50% unionized. If pKa - pH = 0, then 50% of drug is ionized and 50% is unionized. An acid in an acid solution will not ionize. An acid in a basic solution will ionize. 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: built in mic on laptop not working https://cathleennaughtonassoc.com
