Titration of benzoic acid with naoh

WebSolution: The correct answer is D . The pH at the equivalence point in any titration is the pH of the salt solution formed. At the equivalence point of the titration, the solution contains sodium benzoate and water. The passage states that benzoic acid is a weak acid; therefore, its conjugate base, the benzoate anion, is a stronger base than OH ... WebTo determine the volume of NaOH needed to react with the 23.0 mL of HC A 2 H A 3 O A 3, we can use the concept of stoichiometry. First, we can calculate the moles of HC A 2 H A 3 O A 3 in the sample: moles of HC A 2 H A 3 O A 3 = concentration of HC A 2 H A 3 O A 3 × volume of HC A 2 H A 3 O A 3. = 0.105 M × 0.0230 L. = 0.00242 mol.
