The pH of the solution would be 4.73.

This is because acetic acid is a weak acid with a pKa of 4.74. When a weak acid and a weak base are mixed together in equal amounts, the resulting pH will be near the pKa of the weak acid. In this case, acetic acid is the weak acid and the NaOH is the weak base.

Therefore, the resulting pH of the solution would be 4.73, close to the pKa of acetic acid.
