Assume you dissolve 0.235 g of the weak acid benzoic acid, C6H5CO2H, in enough water to make 9.00 multiplied by 102 mL of solution and then titrate the solution with 0.148 M NaOH.
C6H5CO2H(aq) + OH-(aq) = C6H5CO2-(aq) + H2O(l)
What are the concentrations of the following ions at the equivalence point?
Na+, H3O+, OH-
C6H5CO2-
(A) M Na+
(B) M H3O+
(C) M OH-
(D) M C6H5CO2-
(E) What is the pH of the solution?
