17. Acid and Base Equilibrium
pH of Weak Acids
11PRACTICE PROBLEM
Phenypropanoic acid (C9H10O2) is a white, crystalline solid with a sweet floral smell widely used in cosmetics and food flavorings. It is a weak monoprotic base with Ka value of 2.2×10–5. If 750 mg of C9H10O2 is dissolved in 500.0 mL of water, calculate the pH of the solution and the percent ionization.
