Assume you dissolve 0.291 g of the weak acid benzoic acid, C6Hs CO2H, in enough water to make 1.00 Ã 102 mL of solution and then titrate the solution with 0.181 M NaOH, (Ka for benzoic acid-6.3 Ã 10-5.) a. What was the pH of the original benzoic acid solution? b. What are the concentrations of all of the following ions at the equivalence point: Nat, HO, OH, and Na ] - OH c. What is the pH of the solution at the equivalence point? pH-
