A mixture containing 500ml of .1 M HC3H5O2 (acetic acid) and 500 ml of .1 M NaC3H5O2

what is the pH?

2. Relevant equations

can someone walk me through this? i know the answer is 4.89 but im not sure how to get that. im not even entirely sure how to set up the equation

3. The attempt at a solution

i tried this to start, but not sure if its right:

notations:

wa = weak acid

sa = strong acid

wb = weak base

sb = strong base

n = neutral

-wa----sb-------wb-----n

HAc + NaOH <> NaAc + H20

even if this is right, im not sure where to go from here.
