Your TA asks you to make 100 mL of a benzoic acid/benzoate buffer solution of pH = 3.84. The Ka of benzoic acid is 6.5 Ã 10â5 .

a) Determine the volumes of 0.50 M benzoic acid and 0.50 M sodium benzoate required to make 100.0 mL of a pH 3.84 buffer solution.

b) Determine the volumes of 0.50 M benzoic acid and 0.50 M sodium hydroxide required to make 100.0 mL of a pH 3.84 buffer solution.

A buffer is made containing equal concentrations of benzoic acid and sodium benzoate (the salt of the conjugate base for benzoic acid). The Ka value for benzoic acid is 6.5 x 10â5.

Calculate the pH of the solution to two decimal places.

Calculate the pH of a buffer solution that contains 0.25 M benzoic acid (C6H5CO2H) and 0.15 M sodium benzoate (C6H5COONa). (Ka=6.5x10-5 for benzoic acid).
