Assume you dissolve 0.235 g of the weak acid benzoic acid, C6H5CO2H in enough water to make 100 mL of solution and then titrate the solution with 0.108 M NaOH. C6H5CO2H + OH- --> C6H5CO2- + H2)
a. what was the pH of the origianl benzoic acid solution?
b. What are the concentrations of all of the following ions at the equivalecne point: Na+, H3O+, OH-, and C5H5CO2-?
c. What is the pH of the solution at the equivalence point?
