Titration of a weak acid with a strong base. the ph curve for titration of 50.0ml of a 0.100 M of acetic acid with a 0.100 M solution of NaOH (aq). For clarity, water molecules have been omitted from the molecular art.
a) If the acetic acid being titrated here were replaced by hydrochloric acid, would the amount of base needed to reach the equivalence point change?
b) Would the pH at the equivalence point change?
a. yes the pH at the equivalence point will increase.
b. yes the pH at the equivalence point will decrease.
c. no the pH will not change
