A: 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:

C5H5N+H2O⇌C5H5NH++OH−

The pKb of pyridine is 8.75. What is the pH of a 0.340 M solution of pyridine? (Assume that the temperature is 25 ∘C)

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 ionizes in water:

C6H5COOH⇌C6H5COO−+H+

The pKa of this reaction is 4.2. In a 0.62 M solution of benzoic acid, what percentage of the molecules are ionized?

± Determining the pH of a Weak Base and the Percent Ionization of a Weak Acid Unlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency of a weak acid or base to ionize can be quantified in several ways including Ka or Kb, pKa or pKb, and percent ionization*. *This assumes that species of equal concentrations are being compared as percent ionization is affected by concentration. Part A Pyridine is a...
