In the solution containing both 0.10 M acetic acid and 0.10 M
sodium acetate, the acetic acid undergoes ionization. The chemical
equation for this ionization reaction is the same as for a solution
containing acetic acid alone. The difference is that the initial
concentration of acetate ion (before any ionization reaction
occurs) for the solution containing acetic acid alone is zero,
whereas the initial concentration of acetate ion is 0.10 M in your
solution containing both acetic acid and sodium...
