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 quantifled 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 lonizes in water as follows • K, or K. • pK, or pK. • and percent ilonization. CH.N(ag) + H,0() =C,H,NH (ag) + OH (ae) The pK, of pyridine is 8.75 What is the pH of a 0.160 mol L solution of pyridine?

at ionize s or bases partially , the ionic can be quantified 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: CH,COOH(aq) + H,0() = CH,COO (ag) + H3O* (ag) The pK, of this reaction is 4.2. In a 0.58 mol L solution of benzoic acid, what percentage of the molecules are ionized? Express your answer to two significant figures and include the appropriate units. > View Available Hint(s) Value Units percent ionized=
