Determining lonic Strength Part A Unlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency to ionize (i.e., the ionic strength) of a weak acid or base can be quantified in several ways including Pyridine is a weak base that is used in the manufacture of pesticides and plastic resins It is also a component of cigarette smoke. Pyridine ionizes in water as follows The pK, of pyridine is 8.75. What is the pH of a 0.400 M solution of pyridine? Express the pH numerically to two decimal places Hints and percent ionization pH- Submit My Answers Give Up Part B Benzoic acid is a weak acid that has antimicrobial properties. Its sodium salt, sodium benzoate, is a preservative found in foods, medications, and personal hygiene products. Benzoic acid dissociates in water: The pKa of this reaction is 4.2. In a 0.70 M solution of benzoic acid, what percentage of the molecules are ionized? Express the percentage numerically using two significant figures Hints percent ionized = Submit My Answers Give Up
