- Find the pH at the equivalence point of HA being titrated by BOH, where HA is a weak acid with a ka=4.3*10-4 and BOH is a strong base you have
- Building on problem 1, if you have 0.1 M NaOH and find your equivalence point at 23.78 mL added, how many moles of HA were present?
- Find the equivalence point and the pH at equivalence of .234 moles of citric acid being titrated with 0.100 M KOH.
- Acetic acid is vinegar. If you have too much vinegar on your salad, causing a stomach ache where your stomach has a pH of 2.00 and contains 100 mL of liquid, and you take a 1000 mg antiacid (Calcium carbonate), what stage of titration does this put you in? justify your answer with math.
