A student performs the following experiment: 25.0 mL of 0.1 M acetic acid is titrated to the equivalence point with 25.0 mL of 0.1 M NaOH. Calculate the pH at the equivalence point. The equilibrium constant Ka for acetic acid is 1.8*10^-5. Compare this value with the experimental value. Experimental value for acetic acid is pH = 8.8 and volume of base = 24 mL at equivalence point.
