Assume you dissolve 0.235 g of the weak acid benzoic acid, C_{6}H_{5}CO_{2}H, in enough water to make 3.00 ✕ 10^{2} mL of solution and then titrate the solution with 0.163 M NaOH.

C_{6}H_{5}CO_{2}H(aq) + OH^{-}(aq) C_{6}H_{5}CO_{2}^{-}(aq) + H_{2}O(ℓ)

What are the concentrations of the following ions at the equivalence point?

Na^{+}, H_{3}O^{+}, OH^{-}

C_{6}H_{5}CO_{2}^{-}

*M* Na^{+}

*M* H_{3}O^{+}

*M* OH^{-}

*M* C_{6}H_{5}CO_{2}^{-}

What is the pH of the solution?
