Both benzoic acid and the sodium salt of its conjugate base, sodium benzoate, are common preservatives in foods. A food producer wishes to transition from the manufacture of 10-2 M stock solutions of benzoic acid to 10-2 M stock solutions of sodium benzoate by adding NaOH. Estimate the pH of the mixture at the beginning, middle, and end of the transition? The pKa = 4.2. Draw the %3D

Both benzoic acid and the sodium salt of its conjugate base, sodium benzoate, are common preservatives in foods. A food producer wishes to transition from the manufacture of 10-2 M stock solutions of benzoic acid to 10-2 M stock solutions of sodium benzoate by adding NaOH. Estimate the pH of the mixture at the beginning, middle, and end of the transition? The pka = 4.2. Draw the pC-pH diagram labeling all constituents and the pH vs f titration curve sufficiently to cover the entire pH range to answer this question. %3D
