Write reaction equations to explain how acetic acid-acetate buffer reacts with an acid and reacts with a base.

Say, for example, that you had prepared a Buffer C, in which you mixed 1.35 g of sodium acetate, NaC2H3O2, with 100.0 mL of 1.0 M acetic acid.

a. What would be the initial pH of Buffer C?

b. If you add 5.0 mL of 0.5 M NaOH solution to 20.0 mL each of Buffer B and Buffer C, which bufferâs pH would change less? Explain.
