Question: You prepare a buffer solution by dissolving 2.00 g each of benzoic acid, C 6 H 5 COOH, and sodium benzoate, NaC 6 H 5

You prepare a buffer solution by dissolving 2.00 g each of benzoic acid, C₆H₅COOH, and sodium benzoate, NaC₆H₅COO, in 750.0 mL of water.

(a) What is the pH of this buffer? Assume that the solution’s volume is 750.0 mL.

(b) Which buffer component, and how much (in grams), would you add to the 750.0 mL of buffer solution to change its pH to 4.00?
