The samples of nitric and acetic acid shown here are both titrated with a 0.100 M solution of NaOH(aq).


Determine whether each of the following statements concerning these titrations is true or false.
(a) A larger volume of NaOH(aq) is needed to reach the equivalence point in the titration of HNO3.
(b) The pH at the equivalence point in the HNO3 titration will be lower than the pH at the equivalence point in the CH3 COOH titration.
(c) Phenolphthalein would be a suitable indicator for both titrations.
