For the titration of a strong acid with a strong base, which statement below is FALSE? O Past the equivalence point, the pH is due to diluted excess strong basest the equivalence point, the pH is due to diluted excess strong base O Between V =0 mL and the equivalence point, the pH is due to diluted unreacted strong acid. O At V = 0 mL titrant added, the pH is due to initial concentration of strong acid. O The indicator changes color at the end point due to excess acid. At the equivalence point, the pH is due to the auto-ionization of water.
