Problem- In a solution of 108.5 mM acetate buffer (again, this is the concentration of all ionization states of the acetate/acetic acid combined), what is the pH of the solution if the concentration of acetate is 94.9 mM (just the deprotonated state)? The pKa of acetic acid is 4.76. Report your answer to two decimal places.
