Reference no: EM132412914

A buffer solution is made by dissolving 0.214 mol of sodium benzoate in 250 mL of 0.455 M benzoic acid.

a. What is the pH of the buffer solution? (Benzoic Acid has a pKa of 4.19)

pH = pKa + log 10 { [X^-] / [HX] }

b. How could we determine the buffering capacity of this buffer?
