A student is given chloroacetic acid as an unknown weak acid. Calculate the number of milliliters of 0.100 M NaOH required to reach the equivalence point in titration of 0.4840 grams of this acid. What will be the ph at the equivalence point? Assume no additional water has been added beyond the volume of sodium hydroxide used in the titration.
