A buffer solution is prepared by dissolving 1.50 g each of benzoic acid, C 6 H 5

Question:

A buffer solution is prepared by dissolving 1.50 g each of benzoic acid, C₆H₅CO₂H, and sodium benzoate, NaC₆H₅CO₂, in 150.0 mL of solution.
(a) What is the pH of this buffer solution?
(b) Which buffer component must be added, and in what quantity, to change the pH to 4.00?
(c) What quantity of 2.0 M NaOH or 2.0 M HCl must be added to the buffer to change the pH to 4.00?
