A 210.0 mL buffer solution is 0.250 M in acetic acid and 0.250 M in sodium acetate.

1) What is the pH after addition of 0.0050 mol of HCL

2) What is the pH after addition of 0.0050 mol of NaOH

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 buffer’s pH would change less? Explain.

Calculate the volume of 3 M HCl needed to change the pH of 75 mL of the undiluted buffer solution by one pH unit (buffer capacity).

[undiluted buffer solution is prepared by mixing 100 mL of 1.0798 M acetic acid with 100 mL of 1.000 M sodium acetate solution]
