Assume you dissolve 0.235 g of the weak acid benzoic acid, C6H5CO2H, in enough water to make 2.00 ✕ 102 mL of solution and then titrate the solution with 0.168 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-

 _____ M Na+  _____ M H3O+  _____ M OH-  _____ M C6H5CO2- What is the pH of the solution?
