Concentration of acetic acid: 1.041M and concentration of sodium acetate is 1.071M.

The buffer is created by mixing 100mL of acetic acid with 100mL of sodium acetate soluiton.

a) What is the pH of 75mL of the buffer solution after the addition of 1mL of 3M NaOH?

b) What is the pH of 75mL of the buffer solution after the addition of 5mL of 3M NaOH?

c) What is the pH of 75mL of the buffer solution after the addition of 15mL of 3M NaOH?

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

PLEASE SHOW ALL WORK. I DID SOME MISTAKES SOMEWHERE AND WOULD LIKE TO SEE FULL SOLUTIONS TO COMPARE.

Thank you very much.
